          Description

          Allowing nested $or operators would dramatically simplify the logic to build queries. The work of transformation/normalizing the query so that the engine understands it should be done by the server, not the client.

              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).
