Search engine is the core Yandex product. Its goal is to provide a user with the answer to her search query. The search engine uses Yandex's proprietary algorithms to provide relevant structured results presented in an editorially neutral and user-friendly manner. In October 2010 Yandex's share of Russian search market was 64.6%.
Yandex's search technology provides local search results in more than 1,250 Russian cities; also shown are the local results for users in Belarus, Kazakhstan and Ukraine. So called "parallel" search presents on a single page the results from both main web index and specialized information resources, including news, shopping, blogs, images and videos. A user can access Yandex's search engine through personal computers, mobile phones, tablets, and navigation and other digital devices.

It builds a formula based on tens of thousands of factors, which significantly increases the relevance of search results.
