title: Multiple filter for 2sxc module
body: <p>Im looking how to make a search app for 2sxc but with multiple exclusive filter.</p>
  
  <p>If you add more filters results have to be reduced, and if you dont have any filter I need to show all items.</p>
  
  <p>Im looking something similar to <a href="https://2sxc.org/en/Apps" rel="nofollow noreferrer">https://2sxc.org/en/Apps</a> module</p>
  
  <p>Any Idea on how to do it ?</p>
