Sabyasachi Dalal commented on SOLR-281:
---------------------------------------

I am updating the distributed search patch (SOLR-303) with this patch.
I added the dist search components as, 

   <searchComponent name="gstat"     class="org.apache.solr.handler.federated.component.GlobalCollectionStatComponent" />
   <searchComponent name="mqp"     class="org.apache.solr.handler.federated.component.MainQPhaseComponent" />
   <searchComponent name="aqp"     class="org.apache.solr.handler.federated.component.AuxiliaryQPhaseComponent" />

  <requestHandler name="/search" class="solr.SearchHandler">
    <lst name="defaults">
      <str name="echoParams">explicit</str>
    </lst>

    <arr name="last-components">
      <str>gstat</str>
      <str>mqp</str>
      <str>aqp</str>
    </arr>
    
  </requestHandler>

But it was not working.  On debugging i found that these added components were not getting registered.

I made the following change in SolrCore.loadSearchComponents,

    // NamedListPluginLoader<SearchComponent> loader = new NamedListPluginLoader<SearchComponent>( xpath, searchComponents );
    NamedListPluginLoader<SearchComponent> loader = new NamedListPluginLoader<SearchComponent>( xpath, components );
