Sorry, digging further into the code I see I was mistaken. The two indices are 
being combined correctly and the code works in my own tests.

The search looks up the scope index (IDs of all the entries in the target 
scope) and the filter indices and computes their intersection. Not sure why 
this would be so slow in your case.
