Apache Solr SpellChecker Integration with the default select request handler

[Shruthi BN]

Hi Team,

I want to integrate spellcheck handler with default select handler.

Please guide me how can I achieve this.

 

 

I tried like

 

<requestHandler name="/select" class="solr.SearchHandler" startup="lazy">

    

     <lst name="defaults">

       <str name="echoParams">explicit</str>

       <int name="rows">10</int>

       <str name="df">text</str>

                   <!-- Suggest -->

      <str name="df">productname</str>

      <str name="spellcheck.dictionary">default</str>

      <str name="spellcheck">on</str>

      <str name="spellcheck.extendedResults">true</str>

      <str name="spellcheck.count">5</str>

      <str name="spellcheck.collate">true</str>

      <str name="spellcheck.collateExtendedResults">true</str>

     </lst>

                  <arr name="last-components">

      <str>spellcheck</str>

    </arr>

</requestHandler>

 

 

But above code is not working.I got exception like
