title: Ruby on Rails - Search gem that fits my needs
body: <p>I am looking for a search gem and found searchkick really interesting.</p>
  
  <p>I've got a few questions before implementing it</p>
  
  <ul>
  <li>Looked up the internet and didn't find anything about multiple resource search. Is it possible? For example: I have a model Post and User - can I search for them in just one search box? </li>
  <li>would this be a good idea in first case? would a search icon in the navbar make more sense? (click on it and get redirected to search page with multiple search boxes)</li>
  </ul>
  
  <p>thanks</p>
