title: Lucene not giving results when specifying field
body: <p>I have a database which I have indexed in Lucene (using Pylucene) by section (specified by markup in the document) using lucene's fields.  This index seems to work fine.  I can search it using the default field which is simply the entire document and get reasonable results.</p>
  
  <p>The problem is, when I search it using a specific section (not the default), I expect to get a certain number of results back (as specified by <code>IndexSearcher.search(query, results)</code>), but instead it might simply return nothing.  So my question is: how can I get it to return a ranked list with the number of results I specify?</p>
  
  <p>The only place I specify the field is in the QueryParser, by calling:</p>
  
  <pre><code>QueryParser(Version.LUCENE_CURRENT, field, StandardAnalyzer)
  </code></pre>
