title: How advanced can Tibco EMS selectors get?
body: <p>What I am aiming to do in my Bridge Selector is something to the effect of what you see here:</p>
  
  <pre><code>(DC in('2','3','4','5','6','8','9','10','20','21','22','23') AND ActivityType in('Begin Day','End Day','Depart Center','Arrive Center','Payment'))
  OR
  (DC in('2','3','4','5','6') AND ActivityType in('Trip Begin','Trip End'))
  </code></pre>
  
  <p>Shown here in a multi-line format just so it's easier to read.</p>
  
  <p>Is this valid? Is there a large performance hit with having such a complicated selector?
  Any help would be very much appreciated.</p>
