Alan Woodward updated LUCENE-6494:
----------------------------------
Attachment: LUCENE-6494.patch
BufferedSpanCollector is now a private class in NearSpansOrdered, and buffer()
and bufferedCollector() are removed from SpanCollector.
So the public API is now:
* SpanCollector (for collecting data from Spans, for generic use in queries)
* MatchDataCollector (for collecting data from a specific document and query)
* MatchDataIterator (for iterating over the results of a MatchDataCollector)
> Make PayloadSpanUtil apply to other postings information

> With the addition of SpanCollectors, we can now get arbitrary postings
> information from SpanQueries. PayloadSpanUtil does some rewriting to convert
> non-span queries into SpanQueries so that it can collect payloads. It would
> be good to make this more generic, so that we can collect any postings
> information from any query (without having to make invasive changes to
> already optimized Scorers, etc).
