-------------------------------------------------------------
There is still the risk, that duplications appear in the excerpt because there
is a highlighting hit in :fulltext and one for example in full:bar. To prevent
that, it probably makes sense to first do the highlighting on :fulltext fields
when analyzeFulltext is enabled and only if that hasn't been success full we
fallback to the logic of highlighting full: fields. wdyt?

> rep:excerpt not working for content indexed by aggregation in lucene
> --------------------------------------------------------------------
>
> Key: OAK-6597
> URL: https://issues.apache.org/jira/browse/OAK-6597
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: lucene
> Affects Versions: 1.6.1, 1.7.6, 1.8
> Reporter: Dirk Rudolph
> Assignee: Chetan Mehrotra
> Labels: excerpt
> Fix For: 1.10
>
> Attachments: excerpt-with-aggregation-test.patch
>
>
> I mentioned that properties that got indexed due to an aggregation are not
> considered for excerpts (highlighting) as they are not indexed as stored
> fields.
> See the attached patch that implements a test for excerpts in
> {{LuceneIndexAggregationTest2}}.
> It creates the following structure:
> {code}
> /content/foo [test:Page]
> + bar (String)
> - jcr:content [test:PageContent]
> + bar (String)
> {code}
> where both strings (the _bar_ property at _foo_ and the _bar_ property at
> _jcr:content_) contain different text.
> Afterwards it queries for 2 terms ("tinc*" and "aliq*") that either exist in
> _/content/foo/bar_ or _/content/foo/jcr:content/bar_ but not in both. For the
> former one the excerpt is properly provided for the later one it isn't.
