Update:
Index intersection is on by default. The query planner currently limits itself to 2 indices at a time, though this limit may increase in the future.
Original Text:
This should support both single and multiple index intersections.
This should support queries that which want to use a covered index; then complex intersections would never need to hit the document to return the values.
A more detailed description of index intersection in a traditional RDMS can be found here:
