[ http://issues.apache.org/jira/browse/LUCENE-627?page=all ]
Yonik Seeley updated LUCENE-627:
--------------------------------
Attachment: highlight_overlap.diff
Here is a patch that makes the tests work after tokens are re-ordered.
I basically keep track of the start and end offsets of what matches, not just
of the TokenGroup, so highlighting is more specific.
Sorry about the messy patch - my IDE collapses the tabs so I don't even see
them (I only realize there are tabs after I do a diff).

> Key: LUCENE-627
> URL: http://issues.apache.org/jira/browse/LUCENE-627

> Issue Type: Bug
> Components: Other
> Affects Versions: 2.0.1

>
> The lucene highlighter has problems when tokens that overlap are generated.
> For example, if analysis of iPod generates the tokens "i", "pod", "ipod"
> (with pod and ipod in the same position),
> then the highlighter will output this as iipod, regardless of if any of those
> tokens are highlighted.
