Depends on how big your total result set is.  I have one program that
always reads all the results, does filtering and special sorting, and
then caches the result set for paging.

If your result sets are huge then that doesn't work well.  But in that
case, it doesn't work that great reading the properties for each result
to find which might be deleted, either.

Might be better to walk the main word index and flag all
word:meta-name:file-number entries for the given file as deleted so the
results are not included in the initial result set in the first place.
