title: solr terms component not returning results
body: <p>I'm trying to do autocomplete using solr's terms component, but I'm not getting any results returned.</p>
  
  <p>my query:</p>
  
  <pre><code>/solr/terms?&amp;terms.fl=autocomplete_field&amp;wt=json&amp;omitHeader=true
  </code></pre>
  
  <p>my schema:</p>
  
  <pre><code>&lt;field name="autocomplete_field" type="text_tag" indexed="true" stored="true" required="false" multiValued="true" termVectors="true" /&gt;
  
  &lt;fieldType name="text_tag" class="solr.TextField" positionIncrementGap="100"&gt;
    &lt;analyzer type="index"&gt;
      &lt;tokenizer class="solr.KeywordTokenizerFactory"/&gt;
      &lt;!-- in this example, we will only use synonyms at query time
      &lt;filter class="solr.SynonymFilterFactory" synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/&gt;
      --&gt;
      &lt;filter class="solr.LowerCaseFilterFactory"/&gt;
      &lt;filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"/&gt;
      &lt;filter class="solr.RemoveDuplicatesTokenFilterFactory"/&gt;
    &lt;/analyzer&gt;
    &lt;analyzer type="query"&gt;
      &lt;tokenizer class="solr.KeywordTokenizerFactory"/&gt;
      &lt;filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/&gt;
      &lt;filter class="solr.LowerCaseFilterFactory"/&gt;
      &lt;filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"/&gt;
      &lt;filter class="solr.RemoveDuplicatesTokenFilterFactory"/&gt;
    &lt;/analyzer&gt;
