title: Regular expression to match text that contains n or more of specified character
body: <p>I need to find lines that contains more than 10 of "," (I have got errors importing CSV, so I need to correct it manually).
  I'm using Notepad++ so I not need to write reqex to match line, only to match comas.</p>
  
  <pre><code>(.*,.*){11,100}   //does not work
  </code></pre>
