I used to have some help with what and how I should add indexes, but it looks like the new mdb backend is not telling me anymore. Is this correct? Anyway to get a warning when some index needs to be set?
bdb_equality_candidates: (xxxx) not indexed bdb_inequality_candidates: (createTimestamp) not indexed etc
