title: Why does increasing the number of values in an IN statement in Cosmos return fewer (zero) results?
body: <p>I have a query, </p>
  
  <pre><code>SELECT c FROM c JOIN a IN c.some_id WHERE a IN ("some_value")
  </code></pre>
  
  <p>This returns 1 document (expected)</p>
  
  <p>I write another query,</p>
  
  <pre><code>SELECT c FROM c JOIN a IN c.some_id WHERE a IN ("some_value", "another_value")
  </code></pre>
  
  <p>This returns 0 values (unexpected)</p>
  
  <p>Why is this?</p>
