title: Is there a smarter way to reindex elasticsearch?
body: <p>I ask because our search is in a state of flux as we work things out, but each time we make a change to the index (change tokenizer or filter, or number of shards/replicas), we have to blow away the entire index and re-index all our Rails models back into Elasticsearch ... this means we have to factor in downtime to re-index all our records.</p>
  
  <p>Is there a smarter way to do this that I'm not aware of?</p>
