# YandexComBot

> Indexes content for Yandex search in languages other than Russian. Yandex documents that it can index content when there is no explicit robot-specific restriction — a * group is not one.

## What blocking it costs you

You leave Yandex's non-Russian index. A rule naming this token is the only one that works on it.
