title: Can I specify a hibernate relationship with a filter?
body: <p>I have a foo that has a relationship to many bar's.</p>
  
  <p>When I delete bar's in my system I want to keep them in the database for some crazy business reason so I just set a deleted field to true.</p>
  
  <p>Can I specify in my hibernate mapping that I only want my collection to hold elements where that field is false?</p>
