title: Query message store of mirth connect
body: <p>Can I use mirth connect to store millions of HL7v2 messages (pipe delimited) and query them programmatically by our third party software application at a later point of time?</p>
  
  <p>What's the best way to do that? Is mirth's REST API capable to query its message store efficently?</p>
  
  <p>Unfortunatly I need a running mirth connect instance to browse the REST API documentation according to the <a href="https://bridge.nextgen.com/media/3244/NextGen%20Connect%203.7%20User%20Guide.pdf" rel="nofollow noreferrer">manual</a> at page 368. (<em>If it wouldn't require to have a running instance of mirth to browse the documentation of the REST API I wouldn't have asked that question. Is there a mirth connect instance available on the internet to play with? Or would somebody be so kind to post the relevant REST API documentation for that question?</em>)</p>
  
  <p>So far, those are the scenarios I came up yet:</p>
