Ranking syntax for FTS does not yet exist. Some ideas were spread and discussed
in the mailing list, but they have not yet been implemented.
See http://www.mail-archive.com/sqlite-users@xxxxxxxxxx/msg25252.html for the
discussion.

At the time of this writing, FTS is able to retrieve a subset of matching
documents quickly, but still leaves the ranking and sorting to applications.
