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.
This sounds very similar to problem I was having, and I had to increase BDB_IDL_LOGN to 18
for the (rebuilt) objectclass index to be used.
