Is there a reason you're not using MySQL's built-in search, available
since 4.2.10?  It's more performant, and has none of the caveats:

Especially since it allows for incremental indexing of new attachment
rows, I know of no reason to prefer Sphinx.

I expect that should work fine.

The "attachments" table is used to index all content in RT.  This
includes textual content, such as the bodies of messages.  As such, it
is impossible for a ticket to not have at least one Attachment record.
