Fulltext search on related entity

[goingUp]

I have an entity, which have relation to contact. I can add contact first name to its text search fields, and it produce SQL like this: contact.first_name LIKE '%str%' It much slower, than when i do full text search in contact entity. Can I somehow specify, that I want to search by contact full text fields (in an entity, related to contact)?
