title: Finding exact match using Lucene search API
body: <p>I'm working on a company search API using Lucene.
  My Lucene company index has got 2 companies:
  1.Abigail Adams National Bancorp, Inc.
  2.National Bancorp</p>
  
  <p>If the user types in National Bancorp, then only company # 2(ie. National Bancorp) should be returned and not #1.....ie. only exact matches should be returned.
  How do I achieve this functionality?</p>
  
  <p>Thanks for reading.</p>
