title: Combining `where` and `like` statements by using the CI activerecords
body: <p>To cut a long story short: Is it possible and if it is - how can I build a query that looks somewhat like this one</p>
  
  <pre><code>SELECT * FROM a
      WHERE row = 1 AND 
      (other_row LIKE '%..%' OR another_row LIKE '%..%')
  </code></pre>
  
  <p>Basically I cann't come up / find a solution to this problem. I just cann't seem to figure how to add the brackets to the activerecords query. Is that even possible?</p>
  
  <p>My current code:</p>
  
  <pre><code>$data = $this-&gt;where('row', 1)
      -&gt;like('another_row', '...')        
      -&gt;or_where('row', 1)
      -&gt;like('other_row', $search)                
      -&gt;get('a')
      -&gt;result();
  </code></pre>
  
  <p>Result:</p>
  
  <pre><code>SELECT * FROM (`a`) WHERE `row` = 1 OR `row` = 1 AND `another_row` LIKE '%...%' AND other_row` LIKE '%...%'
  </code></pre>
