title: Like search in Elasticsearch
body: <p>I am using elasticsearch for filtering and searching from json file and I am newbie in this technology. So I am little bit confused how to write like query in elasticsearch.</p>
  
  <pre><code>select * from table_name where 'field_name' like 'a%'
  </code></pre>
