title: Build specific where condition using CDbCriteria in Yii
body: <p>How can I build condition like the one below with CDbCriteria?</p>
  
  <pre><code>(
     title LIKE :yc0 
     OR 
     description LIKE :yc0 
     OR 
     tags LIKE :yc0
  ) 
  AND 
  (
     user=:yc1 
     OR 
     user=:yc2
  )
  </code></pre>
  
  <p>I want to do this using only two methods of CDbcriteria, ie, compare() and addSearchCondition() </p>
