Would this be better as four individual filters?
Only if there were likely to occur again in combination with different
constraints.
My guess would be no.
this is because the filter could not be cached?
Since i know it should not cached, is there any way to make sure it does
not purge useful stuff from the cache?
Perhaps you want 2 fields (lat and long) instead of 4?
2 is fine if I was dealing with points, but this is a region, so i need
to deal with a whole region (N,S,E,and W).
One issue here is range queries that include many terms are currently slow.
That's something we need to address sometime (there has been some work
on this in Lucene, but nothing yet committed AFAIK).
do range queries operate on the whole index, or can they be limited
first? That is, if i can throw out half the docs with a simple
TermQuery, does the range still have to go through everything?
thanks
