Configuring additional search components

You can add search components and a handler for the search components. For example, add spell check.

To configure additional search components, add the search component and define it in the handler.

For example, to add the Java spelling checking package JaSpell:

<searchComponent class="solr.SpellCheckComponent" name="suggest_jaspell">
    <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.jaspell.JaspellLookup</str>
      <str name="field">suggest</str>
      <str name="storeDir">suggest</str>
      <str name="buildOnCommit">true</str>
      <float name="threshold">0.0</float>
    </lst>
  </searchComponent>

Configure the parameters for the request handler:

<requestHandler class="org.apache.solr.handler.component.SearchHandler" name="/suggest">
    <lst name="defaults">
      <str name="spellcheck">true</str>
      <str name="spellcheck.dictionary">suggest</str>
      <str name="spellcheck.collate">true</str>
      <str name="spellcheck.extendedResults">true</str>
    </lst>
    <arr name="last-components">
      <str>suggest_jaspell</str>
    </arr>
  </requestHandler>
