title: In Common Lisp how do I search for a sublist within a list
body: <p>If I want to find whether (x 2) exists within a list containing ((x 2) (y 2) (z 2)) for example, how do I do this?</p>
  
  <pre><code>(member '(x 2) '((x 2) (y 2) (z 2))) 
  </code></pre>
  
  <p>returns NIL as does find</p>
  
  <p>Thanks for the help</p>
