search
------
Some stuff for search.
type: type of search. Ignored if PostgreSQL or Sphinx are enabled. Can either
be 'fulltext' (default) or 'like'. The former is faster and more efficient
but requires the lame old MyISAM engine for MySQL. The latter
will work with InnoDB but could be miserably slow on large
systems. We'll probably add another type sometime in the future,
with our own indexing system (maybe like MediaWiki's).
