Nygma search network. Interview - Vladimir Chernyshov, technical director of the intellectual search system Nigma.RF

The Nigma.ru search engine is one of the best search engines. The search engine has a multi-search function. Nigma contains its own resource base, but in addition it allows you to search immediately across all the most popular search engines, including Google, MSN, Yandex, Rambler, AltaVista, Yahoo and Aport. The search engine is located.

Using the Nigma.ru search engine.

Another opportunity of this service may be of interest to schoolchildren and students. Search engine Nigma.ru offers services Nigma math and Nigma chemistry. The first one is for quick solution simple equations and various arithmetic operations, the second allows you to work with formulas of chemical reactions. Search service Nigma recognizes more than a thousand physical, mathematical constants and units of measurement, allowing you to quickly convert from one dimension to another.
pay attention to top line on the Nigma search engine page. Very convenient functions. For example, sending free SMS messages to all leading operators mobile communications, blogs, mail, dictionaries, etc. – get to the pages with one click!

How to search in Nigma.ru?

To improve the quality of the search, you can use special characters (operators) that will indicate to the search engine that certain query words need to be processed in a special way.

Regular queries (without operators).

When you perform a normal multi-word query, search system tries to find, first of all, pages containing greatest number words from the request. That is, in the first places in the list of displayed results there will be pages that have maximum amount words from the request.
For example, the query pink panther will first display pages containing the phrase “pink panther”, then pages that contain both words: “pink” and “panther”, no longer related to each other.

Operators AND, +, AND.

By default, words separated by spaces are considered to be the same as words separated by the operator "+", "AND" or "AND", all of these forms of queries are equivalent (a AND b - we are interested in both the word "a" and word "b").
For example, the queries pink panther, pink+panther, and pink AND panther and pink AND panther will be indistinguishable to a search engine.

Operator OR, OR, ||.

Sometimes some query words are equivalent for you, for example, “download” and “download”. In this case, you can indicate to the search engine using the operators "OR", "OR" and "||" between these words, that it is enough to find pages with any of these words. Pages will be found that contain at least one of the words. Examples: hippopotamus OR hippopotamus, hippopotamus || hippopotamus, mp3 music (download OR download).

Operator "".

If you want to find pages where a given phrase appears, enclose it in quotation marks in your query. This can be useful, for example, when searching for a poem or song lyrics based on a famous line. Compare the results: “frost and sun - a wonderful day” and frost and sun - a wonderful day. The phrase enclosed in quotation marks is searched in its entirety without changing the word order and without taking into account word forms, that is, only exact occurrences of this phrase are found.

Operator - and NOT.

Sometimes the results for some queries provide not only the information you need, but also a lot of other information. For example, the query “windows of growth” will return both results about Soviet-era propaganda posters and about the window manufacturing company of the same name. Let's say we need to find information about posters. Unnecessary results can be filtered using the "-" and "NOT" operators placed before the word you want to exclude from the search results.
Let's clarify the request for "growth windows" using the operators "-" or "NOT": growth windows -pvc -production -via or growth windows NOT pvc NOT production NOT via.

Site operator and site.

If you want to find pages that satisfy a query and are located on a specific site, add the operator "site:site_address" or "SITE:site_address" to the request. You can search multiple sites at once.
The query: nigma site:www.habrahabr.ru will find pages from the site www.habrahabr.ru containing the word “nigma”.
And upon request: news site:lenta.ru, site:utro.ru, news from two sites will be found.
You can specify the site address down to subdomains, for example, the following request: news site:auto.utro.ru specifies a search only on the specified subdomain (auto.utro.ru), results from other subdomains will be ignored.

Complex queries.

Parentheses allow you to group query words so that you can apply an operator to them. For example: Samsung microwave oven (manual OR documentation) The words “manual” and “documentation” are combined in parentheses so that the OR operator applies only to them.

(12th of April). It is unknown whether the choice of such a date was accidental or intentional, but this once again emphasizes the scientific orientation of the search system. For reference, it is worth noting that nygma are spiders of the Dictunidae family, colored greenish, no more than three millimeters long.

System Features

The founder of the project was the former vice president famous company Mail.ru Viktor Lavrenko. A Moscow State University student helped him from the very beginning in creating Nigma. Today the project employs about 15 people.

The Nigma search engine is a kind of laboratory for research. It will be useful to students and with its help they are already defending diplomas and dissertations today. At the same time, like all Internet search engines, Nigma also has a commercial component. For example, search engine results pages contain advertising from Yandex. But the creator of the project still notes that commercial gain was not the main goal of creating this system. The most important thing is efficient search necessary information based on document clustering. Search results are grouped by thematic sites. To do this, the Nigma search system combines all the results obtained from different search engines, using user queries and counters to sort them. For example, the site makes it possible to filter topics that users do not need, which greatly simplifies the search for useful information.

For whom was the Nigma search system created?

Basic user search engine are students. Among other RuNet users, the popularity of the system is at a fairly low level. Of course, the creators of Nigma are interested in promoting their search engine. For this purpose, various events have been and are being carried out. For about a year, Nigma placed its advertisements on Yandex; advertising campaigns on the radio, promotions for particularly active users.

Users can leave feedback on the system's operation or complain about search results using a special form. In addition, surveys are conducted to develop new algorithms and services, functions, including not only search. Systems, for example, correct errors in requests themselves. We can only hope that the creators of Nigma will continue to take into account user opinions in the future.

Index and document base

The Nigma search engine produces results using the database of several machines at once - Rambler, Altavista, Aport, Google, Yahoo, MSN and Yandex. In addition, our own documentary database has been created. In the search results, at the user's request, documents are generated, grouped by topic. This allows you to expand your search conditions by unchecking certain descriptions.

Programmers of the Nigma search engine are developing in an effort to advance one more step in the creation of artificial intelligence. Their main task is to create software for solving intellectual problems. In the future, the developed technologies can be used in other areas of human activity.

The subject of today's article will be Nigma - this is an intelligent search system that stands out among all competitors with an unusual search system that allows you to quickly find what you need and sift out the slag.

When discussing search engines in the community of webmasters and optimizers, it is customary to mention Yandex and Google, everything else remains outside the brackets, sometimes they remember mail.ru, but there is no talk of nigma.ru at all.

The question is - why? It's all about traffic. Website owners are interested in traffic from visitors, and Nigma’s share in the RuNet is negligible. Unpopular search engines are of no interest - too few people use them to spend attention and time.

Meanwhile, for simple user networks, the Nigma search engine is much more interesting than its famous competitors.

Intelligent search system

The uniqueness of Nigma.rf (or Nigma Ru) lies not in secret algorithms for ranking web pages, but in the ability to collect, sort and process information in such a way that only the necessary answers appear on the screen and the user does not have to go through site after site, bumping into different GS and non-thematic resources.

It is very convenient, easy to use, and friendly even for non-technical people.

There are special modules that are responsible for non-standard types of information, for example, searching for torrents or solving mathematical problems - I will talk about them in more detail below.

There is a logical filtering of requests, in which only the category of responses that relates to the topic is selected. For example, many phrases have double, triple or more meanings. A regular search will show everything mixed up, but Nigma will recognize your area of ​​interest and delete it.

The search functions are significantly enhanced by the fact that Nigma takes into account search results from other search engines and can compare and combine them, which allows for better results.

Let's talk about all the functions in more detail.

Normal – Unusual search Nygma

It was mentioned above that the search results, among other things, use the data of others, which makes it better and more complete, but this is far from the most interesting element.

Search query syntax – no need to know!

Unlike other search engines, Nigma does not require knowledge of syntax search queries(all kinds of +, quotes, exclamation marks And so on). Most users don't know how to find exact phrases or exclude words using special characters, so it does not apply them when entering key queries.

Here everything is implemented more simply. We click above the search bar “Advanced Search” and in human understandable form we ask detailed conditions search.

Do you want to exclude unnecessary words– write them in the “without words” field. Let’s say when searching for information about lions, using the query “Lion”, you can exclude the word “Tolstoy” and pages about the great writer will not bother you.

Need exact phrase– there is a special field for it. Searching for a specific site is not a problem.

As a hint, here is an example of what syntax would have to be typed manually if there were no ready-made fields.

You can immediately set the search region, the search engines used, the language, the preferred sorting by date, and several more functions that pre-clarify the search results - and all this without any special knowledge.

Query filtering (clustering)

After you have received the results for your request, Nigma.ru gives you the opportunity to filter them in order to remove deliberately unnecessary trash and save the user’s precious time viewing inappropriate pages.

To do this, a list of categories that appear most frequently in the results appears to the left of the search results. Returning to the example with Leo, we see that many sites relate to astrology, but we need animals - we put crosses in front of the horoscope. Clicking the cross again sets a check mark - a required word.

In this way, from the whole variety of pages using a filter, I left only sites about lions of animals and the king of beasts.

Search tips

Unlike competitors, by entering a query in the search bar you don’t even have to go to the results, since search tips automatically provide information on the entered word from Wikipedia.

This is convenient if you come across an unfamiliar term - enter it into the search bar, hover over the hint, and read the answer. There is no need to press Enter.

Isolation of official sites

Nigma’s user-friendly search element is the highlighting of official sites, and a special icon is added to them in the search results. With it you can quickly find the right organization among mountains of network garbage. This feature helps protect the Internet from scammers, since they will not be able to pass off their website as an official one.

File search (music, books, torrent)

Searching the Internet does not always mean searching for sites with information; often users want to download something - books, music, torrent files with films or programs.

In most cases, turning to Google or Yandex for such data turns life into hell, since the search results show everything, but not the places where something can be downloaded.

The Nigma search system uses special modules for these tasks that work specifically for file searches. Music and books are placed in special tabs.

Book search initially selects sites where you can download literature. A music search provides links to ready-made tracks, which means you can listen to them directly in your browser or download them to your computer. By the way, registered users can independently add audio files to the system.

Torrent trackers are not placed in a separate tab. To search for them, Nigma.rf requires entering an additional word in the search bar - “torrent” or “torrent”. All found torrents with this name will be placed in a table indicating the number of uploading and downloading users.

Nigma - mathematics

This is the module for which Nigma is so loved by students and schoolchildren (and will be loved by those who read the article for the first time).

Nigma actually solves problems in mathematics - equations and examples of varying complexity, including logarithms and complex numbers. It’s difficult to call this function a search, since answers are not searched, but counted, but the feature is really cool and unusual.

Moreover, not only the results of the solution are displayed, but also their progress in various ways.

(Click the picture to enlarge)

Not only numeric data input, but also words are accepted for processing. You can write an equation in Russian without numbers and the system will still calculate it (even certain mistakes in words are allowed).

I hope that these opportunities will not reduce the level of education in our country and students will use it only for testing.

Nigma - chemistry

Chemistry is not a separate section, but it works by analogy with Nygma-mathematics. In the search bar, enter substances in words or letters, and the search engine will show all possible chemical reactions between them, supporting the formulas with hints and comments.

Chemistry at school was easy for me, but I know that for many classmates it was such a dark forest that Nygma-chemistry could become the only way out out of him.

Online unit and currency converter

Another feature is the ability to convert various quantities into other units. You can ask to translate the units of measurement of information, for example, by asking the question “how many MB are in 4 GB” we will get the following answer:

Currency conversion possible different countries at the current rate. The system even accepts some common names. It is enough to ask a question in human language and you will find out “how many bunnies are in 5 wooden bunnies”:

When you communicate with Nigma more closely, you begin to believe that artificial intelligence already reality.

Nigma for webmasters - site search

Despite the fact that the greatest interest (in this moment) the intelligent search engine provides users with benefits, but it also has benefits for webmasters.

We are talking about searching the site. If you have read my article on how to do a Yandex site search (), then you understand what I mean we're talking about. If not, then I’ll briefly explain.

We get 2 codes:

• We paste the frame code with the search results onto the created page;
• We paste the search form code into the place on the site where we want to see a line for entering queries.

Index

Nigma searches both in its own index and in the indexes of Google, Yahoo, MSN, Yandex, Rambler, AltaVista, Aport.

Nigma.ru error correction system corrects gross mistakes(Yurey Lushkof), typos, offering the user a choice of not one, but several correction options. Errors related to wrong choice keyboard layout fibgrf - error, (including combinations with other errors). The dictionary of the intelligent search system has been expanded with names famous brands, which the user can type in the query line even in Russian, since Nigma automatically expands the search with an alternative spelling of the brand.

Decoding abbreviations

Nigma.ru has a service for decoding abbreviations. Abbreviations are entered into the search bar and, in parallel with the search for documents, a search for transcripts of abbreviations is carried out. Transcripts that have been confirmed in the found documents are included in the list of clusters. And those transcripts that have not been confirmed by documents fall into a special pseudo-cluster “Abbreviations”. Examples:

• IMHO, and also like this IMHO

Services and tools

Mathematical

The Nigma system allows you not only to perform the simplest arithmetic transformations, but also to solve mathematical problems of varying degrees of complexity. Nigma also recognizes more than a thousand physical and mathematical constants and units of measurement, which allows you to perform operations with many quantities (including solving equations with them) and receive an answer in the required units of measurement. In addition to equations, the system solves all problems typical for search engine calculators and currency converters. However, Nygma can count in fractions and knows commonly used synonyms for currencies. So, for example, you can calculate how much wood is in a dollar. Using the new service, users will be able to solve various mathematical problems (simplify expressions, solve linear and quadratic equations, systems of equations, equations with units of measurement, convert currencies, calculate the modulus of a number, simplify trigonometric expressions, reduce fractions and much more) by entering them directly into search string in the form of strict or non-strict (plain) text.

News

In response to a query, users will see the three most recent news stories directly on the search results page.

The developers indexed and processed data from more than 3,500 media RSS feeds and popular blogs. The site also has a form through which users themselves can add news resources to the search engine index. The news database is updated every 5 minutes. δ

Hints

Autocomplete search string

Firstly, the system offers options based on previous requests from Nigma.ru users.

Secondly, opposite the proposed autocomplete examples, the most relevant sites related to the user’s request are displayed. Now you can go to the desired site without even typing in the request to the end, but only by selecting it from the list and pressing the “right” key, or simply clicking on the link. If the desired site is in the first place in the tooltip, then you can not select it, but go to it only using the “right” key. For example, if you enter two letters: “by” and press the “right” key, the gismeteo website will open.

Thirdly, the developers have made it as easy as possible for the transition to the most popular sites among Nigma.ru users. For example, previously, to get to the Odnoklassniki website, you had to type 13 letters, press Enter, wait for the search results, and then click on the first result. Now nigma.ru users, holding down the “O” key for several seconds and then releasing it, will immediately be taken to the Odnoklassniki website. The same will happen when pressing the keys: “v” (the user will be taken to the site “in contact”), “yu” (“youtube.com”), “z” (“zaitsev.net”), etc. Moreover, the user no need to switch the language - instead of “o” you can click on “j”, and it will also be redirected to the classmates website.

Improved version

In the improved version, the search engine answers the user's questions before he completely enters his question into the search bar. The system offers filling options, taking into account the popularity of previous user requests. To the right of the option is the answer to the question. For example, if you enter a short query, the system itself will select similar query options, immediately offering an answer. For start new version automatic filling the developers used a knowledge base of 12 million questions and answers, which was compiled based on information from Wikipedia.

Tooltips

When choosing the desired option in the search hint, the user can see definitions of the concepts and words that he wants to find. The database contains 340928 definitions. Information is taken from Wikipedia. It is expected to connect other sources of information.

“We are working to ensure that the user does not need to click the “Find” button, select a site, or search for information on the site. A search engine must be able to answer a question before it is fully typed."

Search by music files

Through the “Music” tab, Nygma users will be able to find and immediately listen to their favorite song right on the search results page (“Vivaldi Seasons”). The Nigma.ru search robot finds music files on the Internet and indexes the tags contained in these same files.

When a user searches in the “music” tab, Nigma finds music files, and the user receives direct links to them as results. The search engine has now indexed 1,600,000 audio files. The developers are planning to expand the base next year, 2009.

Story

• Alpha version launched on April 12, 2005
• September 26, 2005 Nigma provided

Hello, dear readers of the blog site. Today we will talk about another search engine, which was once called Nigma, but after the introduction of Cyrillic domains, it underwent a rebranding and is now proudly written in Russian letters - Nigma.rf.

A little earlier you could read my reviews of the mastodons of the Runet search market: Yandex and Google, which ranks second in popularity among the Russian-speaking Internet community. Those reviews were voluminous and commensurate with the scale of these search engines.

I wrote in a little less detail about Mail, which partially uses Google’s results, and about Rambler’s search, which, in turn, has completely become parasites of Yandex.

I touched even less detail on the mastodons from search world bourgeoisie: Yahoo, which now uses Bing's search results, and Bing itself, which has seriously increased its share after assimilation with Yahoo. I also sang a requiem to Aporta, who rested in God’s life and whose domain was sold for a pittance for the purpose of some kind of shop.

The hero of today’s review, in fact, has never been to Olympus or even close to it (unlike the systems mentioned above), but is nevertheless worthy of attention, because he has his own features that others do not have, and despite his modest financial and human resources Nigma continues to exist as a search engine in RuNet and is even trying to expand into the Vietnamese market.

Operating principles and differences of the Nigma search engine

First of all, I want to immediately explain why I called Nigma add-on popular search engines . They have their own search robot, which indexes the Internet (or just Runet), but in addition to their own index database, developers actively use public databases of other systems (at the moment, after Aport fell out of the picture, the only ones left are Yandex, Google, Rambler, Bing, Yahoo, Altavista).

How large the share of Nygma’s base itself is in this variety of data remains a mystery. But relying on fairly modest human resources (several dozen employees, if I’m not mistaken) and, probably, modest financial capabilities, the costs of indexing the RuNet on your own should be small, because otherwise you can easily go down the drain.

Actually, this project and was conceived as a kind of tool that sorts the results into shelves (categories). This action is called Nigma clustering and it means the following. The total output at the user's request is usually monstrous in size, and the search task in this case is to find user documents (links to them with title and ).

But it is not always clear what exactly the user wanted to see in the first places in the search results. In most cases, there is ambiguity (Yandex has recently partially solved this problem with the help of Spectrum technology). Therefore, the developers decided, along with the general search results, to offer users also Nygma filters, which would make it possible to either highlight certain clusters or, conversely, remove some of them from the search results.

This mess looks something like this:

A set of filters is displayed on the left. Clicking in the checkbox opposite the desired cluster leads to its exclusion from the search (a cross is placed), clicking again, on the contrary, leads to the obligatory display of this cluster, and so on in a circle. Thus, in Nigma you can quickly and easily filter out huge search results and increase its relevance for your loved one:

Actually, this was the main idea that prompted the developers to create a new search engine. The concept of creating a search engine was proposed by a former employee of Maila named Lavrenko, and it was implemented by Vladimir Chernyshov, a final-year student of Higher Mathematics and Cybernetics at Moscow State University, and others like him. This was in 2004, and already at the beginning of April 2005 the website Nigma.ru was opened.

He looked quite simple then:

However, I share their sense of humor, which prompted me to write the caption “The smartest search engine,” because sometimes I also capture the inscription “The smartest search engine” on screenshots. best blog”, which sometimes even causes “just” anger in the comments.

Unfortunately, it seems to me that the time to enter the search market was already lost at that time. Nygma's main competitors by this time had already successfully existed and developed for a whole decade. Yandex finally got back on its feet financially, and Google carried out a successful expansion into the Runet search market.

At the beginning, by the way, Nigma had such an advantage over Google as , and could, hypothetically, have dividends from this, using the Google database. But soon the leader of the world search himself became accustomed to Russian morphology and this system no longer had any special trump cards in this aspect.

Its developers had to come up with new features, which eventually became extended tooltips, identification and highlighting of official sites, special add-ons for search results entitled Nigma mathematics and chemistry, as well as a separate search for torrent files and music.

The latter is somewhat dissonant with classic search engines, which are trying in every possible way to distance themselves from such slippery, in the sense of, topics. Because there is always a sea of ​​people willing to milk money from fat cows. But in our case, most likely, the “elusive Joe” principle is at work.

If we go in chronological order, then by 2008 the interface changes slightly and the ability to search in Nigma by music, books (in online libraries), as well as from pictures (well, more precisely from the words in Alt attribute or standing next to them, and not as it is implemented in real). In addition, the ability to use the Aport and Bing index database is added:

Well, in 2010 appearance The site takes on its usual appearance, with the exception of the logo, where the Latin spelling of the search engine is still used:

The development of algorithms is still carried out by people related to Moscow State University, and therefore the presence of such tools as mathematics and chemistry in Nigma.ru is understandable and justified. By the way, these are pretty cool things that many schoolchildren and students use successfully.

Nigma Mathematics, Chemistry and Music

Personally, I will not answer you unequivocally now from which side you can safely approach the discriminant, but my son appreciates the possibility of entering into address bar(and now in the special section “Mathematics”) an equation or mathematical expression and obtaining not only the answer, but, if desired, the course of the solution:

As you can see, I used a text description of the equation (by the way, with an error that was corrected without question, since the system has a spell checker built in by default), because , but it’s much more tedious for me to type a formula with special characters.

However, Nigma-mathematics translated my text into a formula without any problems, found the answer and even offered to look at the progress of the solution (I don’t give a screenshot of it, because it’s big):

There you will also be invited to watch a short video with an excursion into mathematics from an intelligent search engine:

Looks even cooler to me Nygma-chemistry, because I studied it thirty years ago and completely forgot, although it was very easy for me then. It is possible to obtain formulas both from inorganic chemistry and partially from organic chemistry (where there is some kind of darkness in general).

Moreover, queries can be stupidly entered in text, for example, like this (an interesting reaction in the stomach can occur):

Nigma music is also no less cool (a special link “Music” is highlighted for it above the search form), because it allows you to find not only a link to a song upon request, but also listen to it in the built-in player, or even download it to your computer:

When listening, you will be able to see the addresses of sites where these musical compositions take place, indicating the bitrate and download links. By the way, if you want to upload your music files, you will need to register, the form of which is located under the left column with filters.

To questions about the violation of the rights of copyright holders, Nigma representatives answer something like that this search for music files, on the contrary, will help these same copyright holders track those who are trampling on their rights. And there is a reasonable grain in this.

Well, it’s clear that search for a torrent file from Nigma will help copyright holders of video and software products to track the sources of violation of their rights. For some reason separate link they didn’t provide for browsing through torrents, but in the right top corner issue pops up periodically advertising banner, calling for completely free and without registration this type search.

Although, it’s enough just to enter a request in Nigma’s address bar and add the word “torrent” separated by a space, to get a summary table of all the files found, indicating their name, weight, number of peers and seeds, as well as the addresses of the sites where all this wealth was found.

Nigma.ru search tips and other features

Well, it’s also worth mentioning the slightly unusual search tips in this system. IN Lately We are all accustomed to the fact that the search itself often knows what we want to ask it, and as we enter the query in the line, it offers its own options.

This is convenient, but Nigma went even further and in some cases already in the drop-down list of hints tries to give a short or even detailed answer to the query you enter (and who then contextual advertising will click from the search results if all search engines implement the same feature):

I typed in the query “capital f”, after which I was shown a drop-down list with a list of all possible states for this letter indicating their capitals (short answer), and when you move the mouse cursor to one of these short answers, you will be shown a more detailed help based on information taken from .

Please note that I received the answer without pressing Enter at all and without seeing the results for this request (and the advertising along with it). I think it's convenient. Sometimes it’s also convenient to get a price range for product requests (prices are taken from Mail’s Products):

This search engine also works great converter various physical quantities, currencies and other nonsense. Moreover, you can type all this in words and even in jargon. Actually, in articles about that, and, I mentioned similar capabilities of Runet leaders.

How do you like this version of the query in Nigma: “how many bunnies are in a buck?” Well, she says there are so many:

You know, quite often it occurs to me to search on the Internet decoding of one or another abbreviation encountered, but in Yandex or Google results you can’t always see this in the snippet and you have to go to sites, search there and spend extra time.

On Nigma.ru everything is implemented in this regard somewhat more conveniently. When entering an abbreviation in search bar, you will be able to see her most frequent transcript in the left column with filters, and under the Abbreviations spoiler you can find rarer versions of this abbreviation:

If the entered query implies as an answer official site, then Nigma.rf marks it in the tips with the corresponding inscription in brackets, and in the search results in front of its title there will be a hand with a raised thumb (not middle) finger:

The features are pretty nice. They would also receive a wide river of cash injections - then this search engine would sparkle with completely different colors (by the way, they were spinning at one time, but then Yandex decided that it was not appropriate to promote a competitor).

In the meantime, all this remains largely unclaimed, because Nigma's share in the Runet search market extremely small (according to statistics):

There are seventy times fewer transitions from this search engine to sites in the ru domain zone than from the not very popular Mail. Its traffic can be indirectly judged by, but it is even less than that of the site (in RuNet this indicator is very relative, because users have very few Alexa toolbars installed) and actually says nothing.

They have plans entering the Vietnam search market, but the itim.vn project is still in development and is available only by invite, as Nigma developers claim. At the same time, the not unknown one, which began its expansion into Vietnam at about the same time, successfully launched its portal Wada.vn.

As for the audience that is inherent in this search engine, due to the presence of Nigma chemistry, mathematics and music services, one could make an assumption about its extremely low average age. However, at the RIF conference, held more than a year ago, a representative of this system spoke (in my opinion, it was Vladimir Chernyshev) and gave a graph of its age audience in comparison with Yandex:

There are no special differences, as we see. The same applies, by the way, to the gender of visitors (about fifty-fifty). This comparison was important for SEOs, who could approximate the statistical data presented below for Nigma on Yandex or Google. In particular, the percentage various types requests to their system:

And also very interesting data on the distribution of user preferences (CTR) among the first 20 places in the Top:

During one session, a user often clicks on different ads, so the average number of such clicks, as well as the range of positions within which on average these clicks are made, is interesting:

I hope that someone, interested in my description, will pay attention to this search engine, however, in the matter of choosing a “default search”, habit and the presence of little things that have become attached to them often play a primary role. Well, for example, I can’t use Google because they don’t show up there.

It’s nothing, but I’m used to making transitions to familiar sites, which I can easily recognize in Yandex by their favicons, and even if you crack...

Good luck to you! See you soon on the pages of the blog site
