I'm marking it as Fixed.
> WeightedSpanTermExtractor incorrectly treats the same terms occurring in
> different query types
> ----------------------------------------------------------------------------------------------
>
> Key: LUCENE-1285
> URL: https://issues.apache.org/jira/browse/LUCENE-1285
> Project: Lucene - Java
> Issue Type: Bug
> Components: contrib/highlighter
> Affects Versions: 2.4
> Reporter: Andrzej Bialecki
> Assignee: Otis Gospodnetic
> Fix For: 2.4
>
> Attachments: highlighter-test.patch, highlighter.patch
>
>
> Given a BooleanQuery with multiple clauses, if a term occurs both in a Span /
> Phrase query, and in a TermQuery, the results of term extraction are
> unpredictable and depend on the order of clauses. Concequently, the result of
> highlighting are incorrect.
> Example text: t1 t2 t3 t4 t2
> Example query: t2 t3 "t1 t2"
> Current highlighting: [t1 t2] [t3] t4 t2
> Correct highlighting: [t1 t2] [t3] t4 [t2]
> The problem comes from the fact that we keep a Map<termText,
> WeightedSpanTerm>, and if the same term occurs in a Phrase or Span query the
> resulting WeightedSpanTerm will have a positionSensitive=true, whereas terms
> added from TermQuery have positionSensitive=false. The end result for this
> particular term will depend on the order in which the clauses are processed.
> My fix is to use a subclass of Map, which on put() always sets the result to
> the most lax setting, i.e. if we already have a term with
> positionSensitive=true, and we try to put() a term with
> positionSensitive=false, we set the result positionSensitive=false, as it
> will match both cases.
