title: solr suggester not returning any results
body: <p>I've followed the solr wiki article for suggester almost to the T here: <a href="http://wiki.apache.org/solr/Suggester" rel="noreferrer">http://wiki.apache.org/solr/Suggester</a>.  I have the following xml in my solrconfig.xml:</p>
  
  <pre><code>&lt;searchComponent class="solr.SpellCheckComponent" name="suggest"&gt; 
       &lt;lst name="spellchecker"&gt; 
       &lt;str name="name"&gt;suggest&lt;/str&gt; 
       &lt;str name="classname"&gt;org.apache.solr.spelling.suggest.Suggester&lt;/str&gt; 
       &lt;str name="lookupImpl"&gt;org.apache.solr.spelling.suggest.tst.TSTLookup&lt;/str&gt; 
       &lt;str name="field"&gt;description&lt;/str&gt; 
       &lt;float name="threshold"&gt;0.05&lt;/float&gt; 
       &lt;str name="buildOnCommit"&gt;true&lt;/str&gt; 
     &lt;/lst&gt; 
  &lt;/searchComponent&gt; 
  &lt;requestHandler class="org.apache.solr.handler.component.SearchHandler" name="/suggest"&gt; 
     &lt;lst name="defaults"&gt; 
       &lt;str name="spellcheck"&gt;true&lt;/str&gt; 
       &lt;str name="spellcheck.dictionary"&gt;suggest&lt;/str&gt; 
       &lt;str name="spellcheck.onlyMorePopular"&gt;true&lt;/str&gt; 
       &lt;str name="spellcheck.count"&gt;5&lt;/str&gt; 
       &lt;str name="spellcheck.collate"&gt;true&lt;/str&gt; 
     &lt;/lst&gt; 
     &lt;arr name="components"&gt; 
       &lt;str&gt;suggest&lt;/str&gt; 
     &lt;/arr&gt; 
  &lt;/requestHandler&gt; 
  </code></pre>
  
  <p>However, when I run the following query (or something similar):</p>
  
  <pre><code>../suggest/?q=barbequ
  </code></pre>
  
  <p>I only get the following result xml back:</p>
  
  <pre><code>&lt;response&gt;
     &lt;lst name="responseHeader"&gt;
        &lt;int name="status"&gt;0&lt;/int&gt;
        &lt;int name="QTime"&gt;78&lt;/int&gt;
     &lt;/lst&gt;
     &lt;lst name="spellcheck"&gt;
        &lt;lst name="suggestions"/&gt;
     &lt;/lst&gt;
  &lt;/response&gt;
  </code></pre>
  
  <p>As you can see, this isn't very helpful.  Any suggestions to help resolve this?</p>
