Alan Woodward updated LUCENE-6580:
----------------------------------
Attachment: LUCENE-6580.patch
Patch adding a SpanGapQuery that can be added as part of SpanNearQuery's
constructor.
This also adds a Spans.skipToPosition(int) method which GapSpans overrides to
make seeking forward more efficient.
One thing I don't like here is that SpanGapQuery is a top-level SpanQuery, when
it only really makes sense to be used within SpanNearQuery. An alternative
could be to add a builder to SpanNearQuery with an .addGap(int) method, and
make SpanGapQuery a private class.

> SpanNearQuery is not quite an exact Spans replacement for PhraseQuery at the
> moment, because while you can ask for an overall slop in an ordered match,
> you can't specify exactly where the gaps should appear.
