title: Firestore query comparing two arrays without array-contains
body: <p>Is it possible to compare two arrays in a Firestore query without 'array-contains'?</p>
  <p>Something like this:</p>
  <pre><code>    query = query.where(
         &quot;info.currentLocation&quot;,
         &quot;==&quot;,
         currentUserBasicInfo.currentLocation
      );
  </code></pre>
  <p><code>info.currentLocation</code> and <code>currentUserBasicInfo.currentLocation</code> are both arrays with mapped values. I can't change the data structure and I already have an 'array-contains' in the query. Because the two arrays have to be identical for this to run, I feel like there has to be a way to compare two arrays without having to use 'array-contains' or 'array-contains-any' or 'IN'.</p>
  <p>Any suggestions? Is this possible?</p>
