Koji Sekiguchi commented on LUCENE-2482:
----------------------------------------
I think this is an interesting tool. I'm wondering if Solr can call it, as Solr
does merge indexes.
Is there any restrictions on this? I've never looked into deeper it, but for
example, I see isPayloadAvailable() returns always false. Does it mean that it
doesn't support payload?
Can it support multiple Sorts on indexed fields other than stored float field?

> A tool to sort index according to a float document weight. Documents with
> high weight are given low document numbers, which means that they will be
> first evaluated. When using a strategy of "early termination" of queries (see
> TimeLimitedCollector) such sorting significantly improves the quality of
> partial results.
> (Originally this tool was created by Doug Cutting in Nutch, and used norms as
> document weights - thus the ordering was limited by the limited resolution of
> norms. This is a pure Lucene version of the tool, and it uses arbitrary
> floats from a specified stored field).
