Yandex traces its roots to 1990, when Arkady Volozh and Arkady Borkovsky founded Arkadia, a company that developed MS-DOS software for use in patents and goods classification.[citation needed] Their software featured a full-text search with Russian morphology support.[citation needed] In 1993, Arkadia became a subdivision of Comptek International, another company founded by Volozh in 1989.[citation needed]
