How to allow FULLTEXT SEARCH INDEXING to non-admin user?

I've tried searching alot on the net but am not able to find how to allow a user (not admin/owner) to be able to create & populate the FullText Indexing Catalogs on the tables he creates.
Currently although with admin account, I can create FullText Catalogs but I have to provide the permissions to build & populate catalogs to some user, so that he can use FullText Search on his tables.
Please Help

Cheers
