Michael McCandless commented on LUCENE-4312:
--------------------------------------------
+1 to build on payloads, today, to break the chicken/egg situation. This
should just be a {{TokenFilter}} that converts {{PositionLengthAttribute}} into
payloads? Then [~mgibney] could contribute query-time code that can decode
these payloads and implement correct positional queries. Once these prove
useful we can circle back later and optimize how we store position lengths in
the index.
> Index format to store position length per position
