How to use SolrStore as Remote Autocomplete for Semantic Forms[edit]

  1. Edit your Schema.xml
    1. Add new FieldTypes needed for a good Autocompletetion
      <fieldType name="text_suggest" class="solr.TextField" positionIncrementGap="100">
              <analyzer type="index">
                  <charFilter class="solr.MappingCharFilterFactory" mapping="mapping-ISOLatin1Accent.txt"/>

            <filter class="solr.LowerCaseFilterFactory"/>
           </analyzer>
          </fieldType>
      
    2. Add the Fields needed
      <field name="person_suggest" type="text_suggest" indexed="true" stored="true"/>
      <field name="person_suggest_edge" type="text_suggest_edge" indexed="true" stored="true"/>
      <field name="person_suggest_ngram" type="text_suggest_ngram" indexed="true" stored="true"/>
      <field name="Person_s" type="text_auto" indexed="true" stored="true" />
      

      The Field we use in our Wiki is called "Person", so the automatically generated field is called "Person_s", because it's a string. We need do define it on our selfs because the auto generated field is multivalued and this doesn't work with multivalued fields!

    3. Create CopyFields for your new defined Fields
      <copyField source="Person_s" dest="person_suggest" />
      <copyField source="Person_s" dest="person_suggest_edge" />
      <copyField source="Person_s" dest="person_suggest_ngram" />
      
  2. Edit your solrconfig.xml
    <requestHandler name="/suggestPerson" class="solr.SearchHandler">
            <lst name="defaults">
                <str name="echoParams">explicit</str>
                <str name="defType">edismax</str>
                <str name="rows">10</str>
                <str name="fl">Person_s,dbkey,score</str>
                <str name="qf">person_suggest^15 person_suggest_ngram^25.0</str>
                <str name="pf">person_suggest_edge^25.0</str>
                <str name="sort">score desc,dbkey asc</str>
            </lst>
        </requestHandler>
    
  3. Restart your Solr and start a re-index
  4. Edit your Semantic Forms Extension
    1. go to <your-wiki>/extensions/SemanticForms/includes/
    2. Edit SF_Utils.php line 615 before:
      $return_values = array();
      foreach ( $data->sfautocomplete as $val ) {
             $return_values[] = (array)$val;
      }
      return $return_values;
      

      after:

      $return_values = array();
      if ( strpos($external_url_alias, 'solr') === false) {
             foreach ( $data->sfautocomplete as $val ) {
                  $return_values[] = (array)$val;
             }
      } else {        
             foreach ( $data->response->docs as $val ) {
                  $return_values[] = array( "title" => $val->{'Person_s'} );
             }
      }
      return $return_values;
      
  5. Edit your LocalSettings.php
    $sfgAutocompletionURLs['solrPerson'] = "$wgSolrUrl/suggestPerson?q=<substr>&wt=json&indent=true&omitHeader=true";
    
  6. Edit your Form
    {{{field|Person|input type=textarea with autocomplete|autogrow|values from url=solrPerson}}}
