title: Match all occurrences with window.find()
body: <p>For example if I have a web page HTML like below  </p>
  
  <pre><code>&lt;body&gt;
          Hello Techies, &lt;br&gt;
          Techies here.
  &lt;/body&gt;  
  </code></pre>
  
  <p>If I search for "Techies" using </p>
  
  <pre><code> var sel = window.getSelection(); 
   sel.collapse(document.body, 0); 
   document.body.offsetHeight;
   if (window.find("Techies", true)) { 
     document.execCommand("hiliteColor", false, "YellowGreen"); 
     sel.collapseToEnd(); 
   }
  </code></pre>
  
  <p>It is Highlighting only the first occurred of the "Techies". But when I search with Ctrl+F the first occurrence will be highlighted in Dark and next occurrences will be highlighted in light color mode. How can I achieve the same with the above code.</p>
