Re: Highlighting broken? String index out of range: 35

[Koji Sekiguchi]

I think you are facing this problem:

https://issues.apache.org/jira/browse/SOLR-925
I'm just looking the issue to solve it, I'm not sure that I can fix it 
in my time, though...

Hi everyone,
it seems that I've run into another problem with my Solr setup. :/ The
highlighter just won't highlight anything, no matter which fragmenter or
config params I use.
Here's an example, taken straight out of the example solrconfig.xml:
<requestHandler name="dismax" class="solr.SearchHandler" >
    <lst name="defaults">
     <str name="defType">dismax</str>
     <str name="echoParams">explicit</str>
     <float name="tie">0.01</float>
     <str name="qf">
        text^0.5 features^1.0 name^1.2 sku^1.5 id^10.0 manu^1.1 cat^1.4
     </str>
     <str name="pf">
        text^0.2 features^1.1 name^1.5 manu^1.4 manu_exact^1.9
     </str>
     <str name="bf">
        ord(popularity)^0.5 recip(rord(price),1,1000,1000)^0.3
     </str>
     <str name="fl">
        id,name,price,score
     </str>
     <str name="mm">
        2&lt;-1 5&lt;-2 6&lt;90%
     </str>
     <int name="ps">100</int>
     <str name="q.alt">*:*</str>
     <!-- example highlighter config, enable per-query with hl=true -->
     <str name="hl.fl">text features name</str>
     <!-- for this field, we want no fragmenting, just highlighting -->
     <str name="f.name.hl.fragsize">0</str>
     <!-- instructs Solr to return the field itself if no query terms are
          found -->
     <str name="f.name.hl.alternateField">name</str>
     <str name="f.text.hl.fragmenter">regex</str> <!-- defined below -->
    </lst>
  </requestHandler>

Whenever I try to activate the highlighter, it produces an error:
http://localhost:8983/solr/select/?q=ipod&version=2.2&start=0&rows=10&indent=on&qt=dismax&hl=true

HTTP ERROR: 500

That's what happens with the example setup - on my project it simply won't
highlight anything at all, no matter what I try. :| Can anyone shed some
light on this?
