Is default sphinx.conf 'sql_query' enough?

Hello all,

Isetup RT v4 with fulltext with indexing.I used the default sphinx.conf
where the ‘sql_query’ to fetch data for indexing is like:

/*sql_query = \ SELECT, a.content FROM Attachments a
JOIN Transactions txn ON a.TransactionId = AND txn.ObjectType =
JOIN Tickets t ON txn.ObjectId = \ WHERE a.ContentType =
‘text/plain’ AND t.Status != ‘deleted’

sql_query_info = SELECT * FROM Attachments WHERE id=$id

*/My questionis:

I’d like to fulltext search for patterns/words both in the ‘subject’ and
'body’of an email ticket
from the RT’s web interface ‘Search’ box.Is it possible with the above
configs of sql_query*?If
not please let me know what more should Ineed to add?
