Alan Woodward updated LUCENE-4883:
----------------------------------
Attachment: LUCENE-4883.patch
Here's a preliminary patch, implementing UninvertedFilterReader and cutting
over DocTermOrdsRangeFilter to use it.
Some questions:
- which package should this stuff be in? FieldCache is in o.a.l.search, and
the reader is in o.a.l.index.
- there are a bunch of FieldCache-specific queries and filters. Can these just
be reworked to be DV-specific instead?
- can we consolidate the various Ints, Floats, Shorts etc FieldCache interfaces
into NumericDocValues?
- this still uses the global FieldCache. Should the caches be moved to the
readers instead?
