You probably can get away with this solution as well, but I would like
to suggest you to test Lucene performance before starting optimizing.

If your query on the text of the body/attachments are not huge (my
user end up with rewritten query whose lengths are up to
600KBytes!!!!!!), Lucene will be probably able to return your the
right result much faster than looking in different places for the same

Don't be afraid of the number of documents either; not before testing
on some real data. You could easily find that a simpler architecture
can perform fast enough, and be much more easy to set up and tune.
