Hi Andrea,
I'm using the original highlighter.
Below is my configuration for the highlighter in solrconfig.xml
<requestHandler name="/highlight" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<str name="wt">json</str>
<str name="indent">true</str>
<str name="df">text</str>
<str name="fl">id, title, content_type, last_modified, url, score </str>
<str name="hl">on</str>
<str name="hl.fl">id, title, content, author </str>
<str name="hl.highlightMultiTerm">true</str>
<str name="hl.preserveMulti">true</str>
<str name="hl.encoder">html</str>
<str name="hl.fragsize">200</str>
<str name="hl.maxAnalyzedChars">1000000</str>
<str name="group">true</str>
<str name="group.field">signature</str>
<str name="group.main">true</str>
<str name="group.cache.percent">100</str>
</lst>
</requestHandler>
Have you managed to solve the problem?
Regards,
Edwin
