title: MySQL: Selecting rows ordered by word count
body: <p>How can I order my query by word count? Is it possible?</p>
  
  <p>I have some rows in table, with text fields. I want to order them by word count of these text fields.</p>
  
  <p>Second problem is, that I need to select only these rows, which have for example minimum 10 words, or maximum 20.</p>
