> Project: Lucene - Java

>
> 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).
