> To collect all chunk identifiers (getAllChunkIds) hint is used to force "_id" index usage. 
> This index doesn't help because query is using "lastMod" field. It also doesn't allow to leverage custom indexes if created. In result queries are pretty slow.
> Additionally consider to create index on "lastMod" field to speed-up all queries using this criteria.
