> Querybase is in an experiment and not for production
Also since Firebase doesn't allow more than one filtering field with orderByChild(...) I'm guessing Querybase will do all the work on the client. This is less than ideal since the data has to be downloaded first.
Querybase is also making permutations of all the data you may wish to query. Needlessly taking up space on your server that will have to be retrieved. Wasted bandwidth etc.
