> If the data required is already in the field cache, it seems unnecessary to go to the disk for it, if the data is already in RAM.
> We have a case where we need one field from a large number (500 -1000) of scattered documents in a fairly large index (50-100m docs), and seek time to collect the data from disk is prohibitive, so we'd like to grab the data from the cache, instead.
