Hi Ricardo,

This is a patchset that has been sleeping for some time in my local
git repo. So, I thought it was about time to send it over!

The main change is that some xapian prefixes should be indexed as
boolean prefixes. This makes the use of an implicit AND operator
unneccessary and lets xapian do the natural thing of ordering results
by relevance. I believe this improves the search significantly. Also,
since we retrieve search results by relevance, we can offload limiting
of search results to xapian. Thus, we improve performance as well.

For this patchset to be useful, mumi's xapian index will have to be
rebuilt. In general, it is good to periodically rebuilt the xapian
index from scratch.

Regards,
Arun
