I guess this is my point. If you indexed your tables with Lucene and 
searched on *that* index you would use much less resources and it would 
be much faster. But I was talking about XML, which if search required 
bringing everything into DOMs, it would be much slower and much more 
resource intensive than a RDB.

As for Steve DeRose's stuff -- my brain hurts from reading it...
