["Ryan McKinley (JIRA)" <ji...@apache.org>]

Ryan McKinley commented on SOLR-386:
------------------------------------

How is this different from SOLR-225?

The example solrconfig.xml in trunk includes:


  <highlighting>
   <!-- Configure the standard fragmenter -->
   <!-- This could most likely be commented out in the "default" case -->
   <fragmenter name="gap" class="org.apache.solr.highlight.GapFragmenter" default="true">
    <lst name="defaults">
     <int name="hl.fragsize">100</int>
    </lst>
   </fragmenter>

   <!-- A regular-expression-based fragmenter (f.i., for sentence extraction) -->
   <fragmenter name="regex" class="org.apache.solr.highlight.RegexFragmenter">
    <lst name="defaults">
      <!-- slightly smaller fragsizes work better because of slop -->
      <int name="hl.fragsize">70</int>
      <!-- allow 50% slop on fragment sizes -->
      <float name="hl.regex.slop">0.5</float> 
      <!-- a basic sentence pattern -->
      <str name="hl.regex.pattern">[-\w ,/\n\"']{20,200}</str>
    </lst>
   </fragmenter>
   
   <!-- Configure the standard formatter -->
   <formatter name="html" class="org.apache.solr.highlight.HtmlFormatter" default="true">
    <lst name="defaults">
     <str name="hl.simple.pre"><![CDATA[<em>]]></str>
     <str name="hl.simple.post"><![CDATA[</em>]]></str>
    </lst>
   </formatter>
  </highlighting>

> It would be great if SolrCore allowed the highlighter class to be configurable.  A good way would be to add a +class+ attribute to the <highlighting> element in solrconfig.xml, similar to how the RequestHandler instance is initialized in SorCore.
