title: CAML Query for lookup field with multi values
body: <p>What is the caml query for a Lookup field with multi values?</p>
  
  <p>So far, I am using the following without success (it just throws an error).
  My Lookup column is:</p>
  
  <pre><code>Lookup
  -------
  2;3
  2
  3;4
  
  &lt;Contains&gt;&lt;FieldRef Name="LookupColumn"/&gt;&lt;Value Type="LookupMulti"&gt;2&lt;/Value&gt;&lt;/Contains&gt;
  </code></pre>
  
  <p>What is wrong with that query??</p>
