Subject [jira] Commented: (LUCENE-1500) Highlighter throws StringIndexOutOfBoundsException
Date Fri, 27 Feb 2009 21:13:12 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1500?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12677531#action_12677531
] 

Peter Wolanin commented on LUCENE-1500:
---------------------------------------

The bug we are seeing now happens on pretty much every document that contains multi-byte characters,
but only sometime was it going past the end of the full string and hitting the exception.
  With the patch, the bug is still very evident, it jsut prevents the exception.  I's a serious
flaw in the highlighter - maybe using some only non-utf-8 aware method to calculate string
lengths?

>    Affects Versions: 2.4
>         Environment: Found this running the example code in Solr (latest version).
>            Reporter: David Bowen

> 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.
