What is the minimum privilege required to create a full text index? I just created a full text catalog on my database.  I now have a developer who needs the ability to create full text indexes on the tables in this database.

The suggestion given in a previous question was to grant db owner to the user. I'd really like to avoid giving such a high level of access.

Is there any way to do this without granting dbo? I wasn't able to find anything regarding the permissions aspect on BOL.
Someone can create indexes if they have been granted db_ddladmin or if their user is the owner for that table, database, or has been granted db_owner.
