The study queries to search engines can be interesting not only SEO-experts, and linguists. As it turned out, by analyzing the requested information from the search engines can determine which words that were in use half a century ago, have been preserved in the modern language, and which have fallen into disuse. The result of this study presented on the eve of the company “Yandex”. For the experiment, she used the “Explanatory Dictionary of Russian Language” VI Dahl, published in the years 1866-1868, and requests the service statistics for the last year.

it was found that 60% of the words contained in the published in the years 1863-1866 four-volume dictionary Dahl, still used by Internet users, with half of them are from the regular word search “lexicon”. The other half can be called “leaving” as though they had found in a query, but still much less common, and in many cases, people enter them into the search bar only to find their interpretation.

Curiously, number of common words are now in the network used to have very different values. For example, “porn” was a dialect, means roughly the same thing that “strong” or “strong”; “Dvachom” called object “consisting as it were of the fused twins” (for example, two kernels in the same shell) and “Klubnyak” – “everything klubovatoe forming tangles.”

“Funny” also was used in not quite familiar to our contemporary context, as a noun from the verb “to pin something” rather than “making fun of someone.”

special attention in the study of “Yandex” should be given as map which displays the most characteristic for each of the regions of Russia the word from the dictionary Dahl, who the locals are looking for in Networks are more likely than those living in other regions of the country.
