title: Grouping Unions Together
body: <p>Is it possible to group UNION blocks together? I want to just get a LIMIT for each. Something like</p>
  
  <pre><code>SelectQuery1 LIMIT 1
  UNION
  (SelectQuery2 UNION SelectQuery3) LIMIT 2
  </code></pre>
  
  <p>I want to get the first row in the first query then I want to combine Query2 and Query3 first before getting the first 2 rows.</p>
