title: filter search results from a ThinkingSphinx search in Rails
body: <p>I would like to allow user to search for other users by typing a few keywords in Search box (with ThinkingSphinx as back-end).</p>
  
  <p>After the server returned the search results and display it on View, I want users to be able to click on a dropdown, check on checkboxes to narrow down the results without resubmmitting the query.</p>
  
  <p>Is there a way to filter previous search results WITHOUT having to submit a new query with additional keywords/facets?</p>
  
  <p>Thank you.</p>
