Uwe Schindler updated LUCENE-1487:
----------------------------------
Comment: was deleted
(was: Sorry *EDIT*:
This Filter is really cool on iterating on the FieldCache for StringIndex and
can be even faster for ranges, that are int/float/double/... - so why not
retrofit to our new naming-convention and extend:
- FieldCacheRangeFilter.newTermRange()
- FieldCacheRangeFilter.newByteRange()
- FieldCacheRangeFilter.newShortRange()
- FieldCacheRangeFilter.newIntRange()
- ...
It could because of that also be used on "old" int/long fields of dates, if a
good parser is given (parser that does SimpleDateFormat -> long -> FieldCache
-> direct comparison on this raw numbers). I would try to extend this to all
types and it can be faster than TrieRange, if the range is already in
FieldCache!)
