I picked "Grouping" to try to SQL index since I think it's fairly small. Generated this error:

GT::SQL::Search::MSSQL::Indexer (2108): Problem Creating Full Text Index: Failed to execute query: ' sp_fulltext_catalog 'gforum_Grouping_ctlg', 'create' ' Reason: [Microsoft][ODBC SQL Server Driver][SQL Server]A full-text catalog named 'gforum_Grouping_ctlg' already exists in this database. (SQL-37000)(DBD: st_execute/SQLExecute err=-1) at GT::SQL::Editor::add_search_driver line 696.

Tried it in "User" and "Guest" tables and got this type of error:

GT::SQL::Search::MSSQL::Indexer (3268): Problem Creating Full Text Index: Failed to execute query: ' sp_fulltext_table 'gforum_Guest', 'start_change_tracking' ' Reason: [Microsoft][ODBC SQL Server Driver][SQL Server]Full-text search must be activated on table 'gforum_Guest' before this operation can be performed. (SQL-37000)(DBD: st_execute/SQLExecute err=-1) at GT::SQL::Editor::add_search_driver line 696.

Teach me oh wise one.
