title: How to extend Lucene's StandardAnalyzer for custom special character treatment?
body: <p>I'm using Lucene's StandardAnalyzer for a specific index property.
  As special characters like <code>àéèäöü</code> do not get indexed as expected, I want to replace these characters:  </p>
  
  <ul>
  <li>à -> a</li>
  <li>é -> e</li>
  <li>è -> e</li>
  <li>ä -> ae</li>
  <li>ö -> oe</li>
  <li>ü -> ue</li>
  </ul>
  
  <p>What is the best approach to extend the <code>org.apache.lucene.analysis.standard.StandardAnalyzer</code>class?</p>
  
  <p>I was looking for a way where the standard parser iterates over all tokens (words) and I can retrieve word by word and do the magic there.</p>
  
  <p>Thanks for any hints.</p>
