title: MyBatis "or" criteria
body: <p>I want to create a query with MyBatis, which will produce something like:</p>
  
  <pre><code>SELECT first_field, second_filed, third_field
  WHERE first_field &gt; 1 AND (second_field &gt; 0 OR third_field &lt; 0)
  </code></pre>
  
  <p>How could I construct that with Criteria objects?</p>
