title: Stemming English words with Lucene
body: <p>I'm processing some English texts in a Java application, and I need to stem them.
  For example, from the text "amenities/amenity" I need to get "amenit".</p>
  
  <p>The function looks like:</p>
  
  <pre><code>String stemTerm(String term){
     ...
  }
  </code></pre>
  
  <p>I've found the Lucene Analyzer, but it looks way too complicated for what I need.

  <p>Is there a way to use it to stem words without building an Analyzer? I don't understand all the Analyzer business...</p>
  
  <p><em>EDIT</em>: I actually need a stemming + lemmatization. Can Lucene do this?</p>
