Peter Wolanin commented on LUCENE-1500:
---------------------------------------
Actually, looking at the Lucene source and the trace:
{code}
java.lang.StringIndexOutOfBoundsException: String index out of range: 2822
at java.lang.String.substring(String.java:1765)
at
org.apache.lucene.search.highlight.Highlighter.getBestTextFragments(Highlighter.java:274)
at
org.apache.solr.highlight.DefaultSolrHighlighter.doHighlighting(DefaultSolrHighlighter.java:313)
at
org.apache.solr.handler.component.HighlightComponent.process(HighlightComponent.java:84)
at
org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:195)
at
org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:131)
...
{code}
I see now that getBestTextFragments() takes in a token stream - and each token
in this steam already has start/end positions set. So, this patch would
mitigate the exception, but looks liek the real bug is in Solr.

> Project: Lucene - Java
> Issue Type: Bug
> Components: contrib/highlighter
> Affects Versions: 2.4
> Environment: Found this running the example code in Solr (latest
> version).
> Reporter: David Bowen
> Attachments: patch.txt

>
> Using the canonical Solr example (ant run-example) I added this document
> (using exampledocs/post.sh):
> <add><doc>
> <field name="id">Test for Highlighting
> StringIndexOutOfBoundsExcdption</field>
> <field name="name">Some Name</field>
> <field name="manu">Acme, Inc.</field>
> <field name="features">Description of the features, mentioning various
> things</field>
> <field name="features">Features also is multivalued</field>
> <field name="popularity">6</field>
> <field name="inStock">true</field>
> </doc></add>
> and then the URL
> http://localhost:8983/solr/select/?q=features&hl=true&hl.fl=features caused
> the exception.
> I have a patch. I don't know if it is completely correct, but it avoids this
> exception.
