title: How to build a dictionary for spellchecking in Solr?
body: <p>I'm trying to add spell checking to an existing Solr index.</p>
  
  <p>I've added the following to the <code>solrconfig.xml</code></p>
  
  <pre><code>&lt;searchComponent name="spellcheck" class="solr.SpellCheckComponent"&gt;
    &lt;str name="queryAnalyzerFiedlType"&gt;textSpell&lt;/str&gt;
    &lt;lst name="spellchecker"&gt;
      &lt;str name="name"&gt;my_spell&lt;/str&gt;
      &lt;str name="field"&gt;my_field&lt;/str&gt;
      &lt;str name="buildOnOptimize"&gt;true&lt;/str&gt;
      &lt;str nmae="spellcheckIndexDir"&gt;./spellchecker_my_spell&lt;/str&gt;
    &lt;/lst&gt;
  &lt;/searchComponent&gt;
  </code></pre>
  
  <p>When I try to build the index with <code>http://&lt;myserver&gt;:4103/my_index/select?&amp;spellcheck=true&amp;spellcheck.build=true&amp;spellcheck.dictionary=cn_spell</code></p>
  
  <p>I don't find any evidence that any dictionary is being built, either in the response, or in the file system.</p>
  
  <p>What am I missing?</p>
