title: Updating LuceneIndex entry in Java
body: <p>I'm using lucene indexes for a search feature in an application in Java. Deleting and inserting a new entry in lucene indexes are pretty straight forward, but does anyone know how to update an lucene index entry?</p>
  
  <p>For example the lastname of a person at the moment is "Doe", when I change that to "Doe 1" in my DB, I'll need to update my indexes as well. </p>
  
  <p>The only thing that seems feasible right now is deleting that entry and inserting a new one. But is there any other option for that?</p>
