title: How does Hibernate Search (Lucene indexing) work?
body: <p>I am using Hibernate Search built on top of Lucene indexing. If indexes are created against database table the performance will be good in returning the results.</p>
  
  <p>My question is, once indexes are created, if we query for the results does Hibernate Search fetch results from the original database table using the created indexes? or does it not need to hit the database to fetch the results?</p>
  
  <p>Thanks!</p>
