Where to read about the structure of Yandex domains?

Question

Yandex

Hello!
The task is to partially "kill" Yandex for users (only search is needed, without viewing saved copies). Metrics, advertising, video, mail etc - in the furnace.
The technique allows you to block certain urls (regexp available).
Accordingly, the question arises: is there a description of Yandex domains somewhere?
A huge amount of traffic is generated with Yandex and it’s a little lazy to manually sort out what is what :)
