title: Aggregation with multiple criteria
body: <p>I want to perform aggregation using multiple criteria. The problem is that I don't know how to pass multiple criteria. Do I declare multiple Match operation like below?</p>
  
  <pre><code>MatchOperation matchOperation1 = Aggregation.match(criteria);
  MatchOperation matchOperation2 = Aggregation.match(criteria2);
  </code></pre>
  
  <p>And if yes, then how do I pass them to the aggregation method? I thought that it should be possible to create a MatchOperation that adheres in multiple criteria but I have not found such an example online.</p>
