title: Is @DocumentId required for Hibernate Search?
body: <p>I'm using Hibernate Search and the documentation and books say I need @DocumentId on the id field so that Hibernate Search can know how to map the index to the objects. </p>
  
  <p>My code appears to be working fine without the @DocumentId anywhere in my code. Did Hibernate Search become smart enough to figure out that @Id field is a great default? Are there problems this will cause that are not obvious?</p>
  
  <p>Thanks for your time!</p>
