Subject [jira] Updated: (LUCENE-2692) Position Checking Span Queries
Date Mon, 11 Oct 2010 14:07:32 GMT

Grant Ingersoll updated LUCENE-2692:
------------------------------------

    Attachment: LUCENE-2692.patch

Should be ready to go.  Adds several new span query "position checking" queries.  Not totally
sure on the semantics surrounding the payload checking one, as it is a little awkward right
now handling the differences between SpanNearQuery and all the other ones

> I've created a bunch of new SpanQuery classes that allow one to do things like check
to see if a SpanQuery falls between two positions (which is a more general form of SpanFirstQuery)
and I've also added one that only includes a match if the payload located at the span match
also matches a given payload.  With the latter, one can do queries for items w/ specific payloads.
