I consulted on a project that was using MongoDB even though it was obvious from the concept that an RDBMS would be better, however I went in with an open mind and gave MongoDB a red hot crack. It straight up ignored indexes with no explainable reason why. We had a support contract and they just gave us the run around.

yeah i've had similar experience but never had indexes get ignored! 100% not surprised though.

lord knows i've been through this... glad it's something they finally solved for.
