[jira] [Resolved] (LUCENE-3229) SpanNearQuery: ordered spans should
not overlap
[ https://issues.apache.org/jira/browse/LUCENE-3229?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Erik Hatcher resolved LUCENE-3229.
----------------------------------
Resolution: Fixed
Committed to branches 4_10, 5x, and trunk.
I worry that lucene/CHANGES.txt is a bit off on some of those, so might need to fix those up after the fact.

> While using Span queries I think I've found a little bug.
> With a document like this (from the TestNearSpansOrdered unit test) :
> "w1 w2 w3 w4 w5"
> If I try to search for this span query :
> spanNear([spanNear([field:w3, field:w5], 1, true), field:w4], 0, true)
> the above document is returned and I think it should not because 'w4' is not after 'w5'.
> The 2 spans are not ordered, because there is an overlap.
> I will add a test patch in the TestNearSpansOrdered unit test.
> I will add a patch to solve this issue too.
> Basicaly it modifies the two docSpansOrdered functions to make sure that the spans does not overlap.
