title: How does ElasticSearch handle an index with 230m entries?
body: <p>I was looking through elasticsearch and was noticing that you can create an index and bulk add items.  I currently have a series of flat files with 220 million entries.  I am working on Logstash to parse and add them to ElasticSearch, but I feel that it existing under 1 index would be rough to query.  The row data is nothing more than 1-3 properties at most.</p>
  
  <p>How does Elasticsearch function in this case? In order to effectively query this index, do you just add additional instances to the cluster and they will work together to crunch the set?</p>
  
  <p>I have been walking through the documentation, and it is explaining what to do, but not necessarily all the time explaining why it does what it does.</p>
