Yes. Unless you simply leave them in the collection and use a blacklist of
stale inverted file entries.

Recent work suggests that you have a hierarchy of inverted files. Each file
smaller by a factor than the previous one. You use them in parallel, i.e. you
are running several queries at the same time on different query engines. Then
you merge the results.
A good approximation of such behavior could be achieved by properly hacking
gift-add-collection.pl :-) and properly using the GIFT's elaborate query
engine construction mechanism in gift-config.mrml. The missing bit in such an
approach would be that the statistics about each feature would not be shared
among the huge/large/small/tiny inverted files. This would be not so good for
the ranking, but nothing a small hack couldn't cure ;-) .
Cheers,
Wolfgang
