            We've added in matching for nested or clauses, but not index support. Index support is SERVER-3327.

            I have tried with 1.9.1 development release and night build with nested $or like this. I saw the message as following:
            "failed with exception: exception: 13090 nested $or/$nor not allowed", but I checked the source code(matcher.cpp), this information has been removed. I wonder if the build is not based on latest code. Please check out.

            Xiaofeng - can you send the git hash for the mongod version you are using (this is logged on mongod startup).
