title: Solr case insensitve
body: <p>Hallo, </p>
  
  <p>I'am implementing an autocompletion feature in Solr and have one problem.</p>
  
  <p>For autocompletion I am using </p>
  
  <pre><code>&lt;fieldType name="text_auto" class="solr.TextField" sortMissingLast="true" omitNorms="true"&gt;
      &lt;analyzer&gt;
          &lt;tokenizer class="solr.KeywordTokenizerFactory"/&gt;  
          &lt;filter class="solr.LowerCaseFilterFactory" /&gt;
      &lt;/analyzer&gt;
  &lt;/fieldType&gt; 
  </code></pre>
  
  <p>I thought that the LowerCaseFilter should make the Token Case insensitiv but that ist wrong. In fact in just lowercases the Token which means that a query like "comput" would lead to "computer" while "Comput" doesn't. 
  Actually I want comput and Comput to lead to Computer. </p>
  
  <p>I allready tried this:</p>
  
  <pre><code>&lt;fieldType name="text_auto_low" class="solr.TextField" sortMissingLast="true" omitNorms="true"&gt;
      &lt;analyzer&gt;
          &lt;tokenizer class="solr.KeywordTokenizerFactory"/&gt;  
          &lt;filter class="solr.LowerCaseFilterFactory" /&gt;
      &lt;/analyzer&gt;
  &lt;/fieldType&gt; 
  
  &lt;fieldType name="text_auto_up" class="solr.TextField" sortMissingLast="true" omitNorms="true"&gt;
      &lt;analyzer&gt;
          &lt;tokenizer class="solr.KeywordTokenizerFactory"/&gt;  
      &lt;/analyzer&gt;
  &lt;/fieldType&gt;
  </code></pre>
  
  <p> 
   
   </p>
  
  <p>For some reason it doesn't word either. My question is why and haw can I fix this?</p>
