David Smiley created LUCENE-6139:
------------------------------------
Summary: TokenGroup.getStart|EndOffset should return
matchStart|EndOffset not start|endOffset
Key: LUCENE-6139
URL: https://issues.apache.org/jira/browse/LUCENE-6139
Project: Lucene - Core
Issue Type: Bug
Components: modules/highlighter
Reporter: David Smiley
The default highlighter has a TokenGroup class that is passed to
Formatter.highlightTerm(). TokenGroup also has getStartOffset() and
getEndOffset() methods that ostensibly return the start and end offsets into
the original text of the current term. These getters aren't called by Lucene
or Solr but they are made available and are useful to me. _The problem is that
they return the wrong offsets when there are tokens at the same position._ I
believe this was an oversight of LUCENE-627 in which these getters should have
been updated but weren't. The fix is simple: return matchStartOffset and
matchEndOffset from these getters, not startOffset and endOffset. I think this
oversight would not have occurred if Highlighter didn't have package-access to
TokenGroup's fields.
