title: Regular Expressions: Is there an AND operator?
body: <p>Obviously, you can use the <code>|</code> (pipe?) to represent <code>OR</code>, but is there a way to represent <code>AND</code> as well?</p>
  
  <p>Specifically, I'd like to match paragraphs of text that contain ALL of a certain phrase, but in no particular order.</p>
