title: Bonsai automatic indexing
body: <p>I use MongoDb for storage with an express, Heroku-hosted app.</p>
  
  <p>I would like to provide search capabilities to some MongoDb collections, using ElasticSearch via the <a href="https://bonsai.io/" rel="nofollow">Bonsai</a> Heroku add-on.</p>
  
  <p><em>However, according to the <a href="https://bonsai.io/faq" rel="nofollow">Bonsai faq</a>, Elasticsearch River plugins are not supported.</em></p>
  
  <p>How can I automatically re-index my MongoDb collections (when a MongoDb document is created/updated/deleted) on Bonsai, using custom mapping, if I cannot use <a href="http://elasticsearch-river-mongodb" rel="nofollow">elasticsearch-river-mongodb</a>?</p>
