You might want to read up on the query planner: http://www.sqlite.org/queryplanner.html#searching The short of it: only one btree index will be used per source table. > Is this a limitation of SQLite or a bug?

There exist other types of indexes (for example bitmap indexes [1]), which have different properties and can be combined to resolve a query, but such structures are not supported by SQLite.
