Robert Muir commented on SOLR-4137:
-----------------------------------
Thanks Marcel. Its useful to know (but I'm sorry you are having to deal with
it), that these failures
are not just theoretical but happening in real life.
We have a test that finds these bugs and documents a list of broken analyzers
(http://svn.apache.org/repos/asf/lucene/dev/trunk/lucene/analysis/common/src/test/org/apache/lucene/analysis/core/TestRandomChains.java)
You can see e.g. WordDelimiterFilter, HyphenatedWordsFilter, etc on these lists
and also in your chain.
Due to the specific error, I think its WordDelimiterFilter in this case.
its time to start fixing these buggy analyzers! Thanks for reporting this.
> FastVectorHighlighter: StringIndexOutOfBoundsException in BaseFragmentsBuilder
> ------------------------------------------------------------------------------
>
> Key: SOLR-4137
> URL: https://issues.apache.org/jira/browse/SOLR-4137
> Project: Solr
> Issue Type: Bug
> Components: highlighter
> Affects Versions: 3.6.1
> Reporter: Marcel
>
> under some circumstances the BaseFragmentsBuilder genereates a
> StringIndexOutOfBoundsException inside the makeFragment method.
> The starting offset is higher than the end offset.
> I did a small patch checking the offsets and posted it over there at
> Stackoverflow:
> http://stackoverflow.com/questions/12456448/solr-highlight-bug-with-usefastvectorhighlighter
> The code in 4.0 seems to be the same as in 3.6.1
> Example how to reproduce the behaviour:
> There is a word called "www.DAKgesundAktivBonus.de" inside the index. If you
> search for "dak bonus" some offset calculations went wrong.
