I have an index with single mapping and almost all fields with doc\_values=true. Fisrt time after adding doc\_values filddata contains only boolean fields. But now stats shows that all those fields present in fielddata cache. Not only string and boolean fields but numeric too.
And I have the frustration of how this could happen.

I'm sorry, system administrator gave me mapping from another cluster. So all is ok.
