title: MongoDb c# driver 2.0 Any in many to many
body: <p>I have the following issue - how to check is there are any element from <code>int</code> array <code>mailListIds</code> contains in <code>MailLists</code> in <code>MailListId</code> field. I think it could be something like the following :</p>
  
  <pre><code>Builders&lt;Profile&gt;.Filter.AnyIn(p =&gt; p.MailLists.Select(m =&gt; m.MailListId), mailListIds)
  </code></pre>
  
  <p>But that code cannot be serialized into query. How to implement it ?</p>
