Subject [jira] [Created] (LUCENE-3370) Support for a "SpanNotNearQuery"
Date Wed, 10 Aug 2011 06:11:27 GMT
Support for a "SpanNotNearQuery"
--------------------------------

                 Key: LUCENE-3370
                 URL: https://issues.apache.org/jira/browse/LUCENE-3370
             Project: Lucene - Java
          Issue Type: New Feature
          Components: core/search
            Reporter: Trejkaz


Sometimes you want to find an instance of a span which does not hit near some other span query.
 SpanNotQuery only excludes exact hits on the term, but sometimes you want to exclude hits
1 away from the first, and other times you might want the range to be wider.

So a SpanNotNearQuery could be useful.  

SpanNotQuery is actually very close, and adding slop+inOrder support to it is probably sufficient
to make a SpanNotNearQuery. :)

There appears to be one project which has done it in this fashion, although this particular
code looks like it's out of date:
