title: elastic search create time based indices
body: <p>According to <a href="https://www.elastic.co/guide/en/elasticsearch/guide/current/time-based.html" rel="nofollow">Time-Based Data</a>, there are mainly two situations to use this kind of method. First it is for logging, es is integrated with Logstash which is default to create a new indices for every day. </p>
  
  <p>However I am in the second condition creating indices for social network activity, and the indices will be created every 3 month automatically, which means the indices name will be <strong>data-01</strong>, <strong>data-04</strong>, <strong>data-07</strong>. </p>
  
  <p>I have search elastic <a href="https://www.elastic.co/guide/en/elasticsearch/reference/current/index.html" rel="nofollow">elastic search reference2.1</a> and <a href="https://www.elastic.co/guide/en/elasticsearch/guide/current/index.html" rel="nofollow">elastic search : The Definitive Guide</a> a lot. I have got nothing helpful.</p>
  
  <p>Hopes anyone who can give me a clue or tips.</p>
