title: Cloud Firestore Case Insensitive Sorting Using Query
body: <p>I tried to read sorted data from Cloud Firestore using <strong>OrderBy</strong>.
  And Firestore returned data as Following Order:</p>
  
  <p><strong>AAA<br/>
  BBB<br/>
  aaa<br/>
  bbb</strong></p>
  
  <p>Now, what I want is something like following:</p>
  
  <p><strong>AAA<br/>
  aaa<br/>
  BBB<br/>
  bbb</strong></p>
  
  <p>I want this result only using <strong>OrderBy</strong> not by manual Sorting.<br/>
  Is there any way to sort like this in Firestore?<br/><br/><br/>
  Please provide me a solution for this.</p>
  
  <p>Thanks in Advance.</p>
