Subject [jira] Updated: (SOLR-1395) Integrate Katta
Date Wed, 10 Nov 2010 02:14:23 GMT


tom liu updated SOLR-1395:

    Attachment: solr-1395-katta-0.6.2-3.patch

fixed some bugs:
# select?qt=qtname do not supported in SolrKattaServer of subproxy
in SolrKattaServer, any queryHanlder must be MultiEmbeddedSearchHandler.
so in solrconfig.xml, we must change solr.SearchHandler to MultiEmbeddedSearchHandler
for example:
  <searchComponent name="tvComponent" class="solr.TermVectorComponent"/>
  <!-- A Req Handler for working with the tvComponent.  This is purely as an example.
  You will likely want to add the component to your already specified request handlers. -->
  <requestHandler name="tvrh" class="solr.MultiEmbeddedSearchHandler">
    <lst name="defaults">
      <bool name="tv">true</bool>
    <arr name="last-components">
# TermVectorComponent do not return results
