title: Spring data - $regex - is there an or?
body: <p>I use this method in order to find products:</p>
  
  <pre><code>@Query("{ 'name' : { $regex: ?0 }, 'number' : { $regex: ?1 } }")
  List&lt;Product&gt; findProductByRegex(final String searchString, final String number);
  </code></pre>
  
  <p>I can not find products where name or number contains a term.
  Is there an or conjunction with @Query?</p>
