You are correct on that point, but it seems rather difficult for you
to do the range caching and have it work across any document updates
(unless a lot more notification interfaces are added to Lucene), so I
guess I don't see the point of your caching.
Given, a sample date range:
01/01/2001 to 01/01/2007
has a bit set associated.
If I did a query for
12/31/2000 to 01/01/2007
the current filter code would cause a new filter to be created (which
is what I assume you are attempting to solve). Under you solution I
would end up
with 2 filters
12/31/2000 to 01/01/2001 and 01/01/2001 to 01/01/2007
the problem is that the documents that match 12/31/2000 to 01/01/2001
could be all other index - necessitating sparse bit sets, but even
then I guess I don't see the benefit, unless you REALLY know your
dataset, and if you do you could just create all of the needed
filters ahead of time (but you would still need the code I added if
your index changes at all).
From my understanding of the Lucene design, filters are designed for
common, frequently reused queries terms. if you attempt to trun
everything into a filter I think you are going to have a hard time.
I may have a poor understanding of what you are trying to do though.

Thanks for the pointer, Robert.
Was that the "MultiSegmentQueryFilter enhancement for interactive
indexes?" thread?
If so, was that not a solution to caching sets in the event of
variable index content rather than my approach which is for caching
sets in the event of variable query ranges? Maybe a mix of the 2
approaches is required?
Cheers
Mark
