Subject Re: Derive suggestions across multiple fields
Date Wed, 03 Jun 2015 10:07:19 GMT
This is my suggester configuration:

  <searchComponent class="solr.SpellCheckComponent" name="suggest">
    <lst name="spellchecker">
      <str name="name">suggest</str>
      <str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
      <str
name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookupFactory</str>
  <str name="field">text</str>  <!-- the indexed field to derive
suggestions from -->
      <float name="threshold">0.005</float>
      <str name="buildOnCommit">true</str>
    </lst>
  </searchComponent>
  <requestHandler class="org.apache.solr.handler.component.SearchHandler"
name="/suggest">
    <lst name="defaults">
       <str name="echoParams">explicit</str>
  <str name="defType">edismax</str>
       <int name="rows">10</int>
       <str name="wt">json</str>
       <str name="indent">true</str>
  <str name="df">text</str>

      <str name="spellcheck">true</str>
      <str name="spellcheck.dictionary">suggest</str>
      <str name="spellcheck.onlyMorePopular">true</str>
      <str name="spellcheck.count">5</str>
      <str name="spellcheck.collate">true</str>
    </lst>
    <arr name="components">
      <str>suggest</str>
    </arr>
  </requestHandler>


Yes, I've read the guide. I've found out that there is a need to do
re-indexing if I'm creating a new copyField. It works when I used the
copyField that's created before the indexing is done.

As I'm using the spellcheck dictionary as my suggester, so does that mean I
just need to build the spellcheck dictionary?


Regards,
Edwin
