Let me comment on that. We did not yet add indexes to the BDII because of contradictory evidence and worries about the overall effect: each index will speed up a particular query, but it also takes a possibly significant amount of CPU time to create the index, which may slow down the BDII operation! This is a concern for very busy top-level BDIIs like lcg-bdii.cern.ch. Last week we discussed doing some experiments to decide which indexes should be added. I suspect we will essentially implement Valentin's recommendations.
