title: Searching multiple files for multiple words
body: <p>I have to search trough a huge amount of <code>.txt</code> files. I know I can do multiple words search, but here's my problem. I want my results to only be the <code>.txt</code> files that contain all of the words of the search entry.</p>
  
  <p>For example:</p>
  
  <p><strong>File 1</strong>:</p>
  
  <pre><code>test1
  </code></pre>
  
  <p><strong>File 2</strong>:</p>
  
  <pre><code> test1
   test2
  </code></pre>
  
  <p>Search files for <code>test1</code> and <code>test2</code> will only result in showing File 2.</p>
  
  <p>Hope someone can help me out.
  Thanks</p>
