title: ClearCase: Find elements containing one of several attributes
body: <p>On ClearCase I use the following command to find all the elements that have the <code>foo</code> attribute with the value <code>"yes"</code>:</p>
  
  <pre><code>cleartool find . -ver 'foo == "yes"' -print
  </code></pre>
  
  <p>Is there a way to retrieve in a single command the elements that have the <code>foo</code> attribute with the value either <code>"yes"</code> <strong>or</strong> <code>"maybe"</code>?</p>
