title: How to match multiple words in regex
body: <p>Just a simple regex I don't know how to write.</p>
  
  <p>The regex has to make sure a string matches all 3 words. I see how to make it match <em>any</em> of the 3:</p>
  
  <pre><code>/advancedbrain|com_ixxocart|p\=completed/
  </code></pre>
  
  <p>but I need to make sure that <em>all</em> 3 words are present in the string.</p>
  
  <p>Here are the words</p>
  
  <ol>
  <li>advancebrain</li>
  <li>com_ixxocart</li>
  <li>p=completed</li>
  </ol>
