title: Not analysed query on analysed field
body: <p>I have certain document which stores the brand names in analysed form for ex: {"name":"Samsung"}
  {"name":"Motion Systems"}. There are cases where i would want a term search starting with "s" which should result in both the documents. and another case where i want only the complete field starting with "s" query which results in only "samsung" returned.
  I have analysed the name field and stored it. Is there any way in which i can do the complete field starting with query in elastic search?</p>
