How to disable indexing of the site specific search engine?

In connection with the recent events in Russian IT was sick to see one administered site in the results of one search engine, and only her. As I understand it, it needs some way to prevent the indexation of site by search robots that system. Is there intended to do some settings, for example, in robots.txt? Or a list of User-Agent the search engines which content you can not give?
