Re: or-ing to QuerySets turns INNER into LEFT OUTER joins?


This is still about 50 times better than the form with Q objects and
LEFT OUTER joins.

  This is rather unusual. A join in the database should be quite a bit faster than doing things manually, except if the joined tables produce massive amounts of data. This suggests that you're missing useful indexes and/or statistics for your query.
