title: REST RQL Java Implementation
body: <p>Is there any java implementation of "RQL" (Resource Query Language), there is an implementation of "FIQL" (Feed Item Query Language) <a href="http://cxf.apache.org/docs/jax-rs-search.html">here</a> but it is part of CXF, so my questions are :</p>
  
  <ol>
  <li>Can I use the FIQL engine of CXF implementation separably from using CXF, in case I'm using Spring MVC</li>
  <li>Is there implementation of RQL </li>
  <li>RQL vs FIQL </li>
  </ol>
