title: matching all characters in any order in regex
body: <p>I'm a regex newbie, but I understand how to match any characters in a regex query in order (ex. [abc] will match any of a, b or c.  Also, I believe "abc" will match abc exactly).</p>
  
  <p>However, how do I construct a regex query that will match all the characters abc in any order?  So for example, I want it to match "cab" or "bracket".  I'm using Python as my scripting language (not sure if this matters or not).</p>
