You can tell SQLite to search for different rows or order them in a different 
order.  But you cannot tell SQLite to use a particular algorithm to do those 
things.  SQLite decides how to obey your instructions itself.  The best thing 
you can do is to CREATE an INDEX ideally suited to your SELECT command.

If your database is large and you are concerned about how long your operations 
may take you might like to execute the ANALYZE command after you have INSERTed 
your data in the database and CREATEd your INDEX(es):

Hope this helps.
