title: cakephp complex query multiple 'OR' condition
body: <p>i want to make query like this with cakephp:</p>
  
  <pre><code>WHERE text LIKE '%keyword%' 
  AND 
  (
      (text LIKE '%something%') 
      OR (text LIKE '%something%') 
      OR (...)
  ) 
  AND 
  (
      (text LIKE '%other%') 
      OR (text LIKE '%other%') 
      OR (...)
  ) 
  NOT 
  (
      (text LIKE '%dont include%') 
      OR (text LIKE '%dont include%') 
      OR (...)
  )
  </code></pre>
  
  <p>this is my code for $conditions:</p>
  
  <pre><code>$conditions = array
  (
      'Tweet.text LIKE' =&gt; '%keyword%',
      'AND' =&gt; array(
          array(
              'OR' =&gt; array(
                  // topic
                  array('Tweet.text LIKE' =&gt; '%something%'),
                  array('Tweet.text LIKE' =&gt; '%something%')
              )
          ),
          array(
              'OR' =&gt; array(
                  // sentiment
                  array('Tweet.text LIKE' =&gt; '%other%'),
                  array('Tweet.text LIKE' =&gt; '%other%')
              )
          )
      ),
      'NOT' =&gt; array(
          array('Tweet.text LIKE' =&gt; '%dont include%'),
          array('Tweet.text LIKE' =&gt; '%dont include%')
      )
  );
  </code></pre>
  
  <p>i am displaying the result with Debugger::dump() method, and the result is just using the last 'OR' condition, not both 'OR' conditions:</p>
  
  <pre><code>array(
      'Tweet.text LIKE' =&gt; '%keyword%',
      'OR' =&gt; array(
          (int) 0 =&gt; array(
              'Tweet.text LIKE' =&gt; '%other%'
          ),
          (int) 1 =&gt; array(
              'Tweet.text LIKE' =&gt; '%other%'
          )
      ),
      'NOT' =&gt; array(
          (int) 0 =&gt; array(
              'Tweet.text LIKE' =&gt; '%dont include%'
          ),
          (int) 1 =&gt; array(
              'Tweet.text LIKE' =&gt; '%dont include%'
          )
      )
  )
  </code></pre>
  
  <p>My question is, how do I make a query such that use both 'OR' condition?</p>
  
  <p>Pls reply as soon as possible.. Thanks in advance :)</p>
