title: Regex containing (or not) whole words
body: <p>I would like to have a regex matching "house", "black house"... (* house), but not "white house".</p>
  
  <blockquote>
    <p>\b^(white)\b* house</p>
  </blockquote>
  
  <p>That was one of my tries, but it does not match what I need. Any ideas?? Thanks!</p>
