Yanex (Russian: Я́ндекс) is a Russian search engine and one of the largest Russian Web portals. Yandex was launched in 1997. Its name can be explained as "Yet Another iNDEXer" (yandex) or "Языково́й (language) Index". The Russian word "Я" corresponds to English "I" (as the singular first-person pronoun), making "Яndex" a bilingual pun on "Index".
