title: indexing numeric field as both int and string in elastic search
body: <p>How can I index a numeric field as both a integer and string using multi_field . As multi_field is deprecated now. How can I achieve the same using the "fields" field in version 2.x. I have heard that a field can be indexing and analysed in different ways using "fields". But can it be indexed as different types in elastic search?</p>
  
  <p>The issue that I am facing is the classical numeric field search highlighting issue in elastic search.where I could not get numeric fields highlighting. So I want to index the field as string and int so that I can search, highlight and perform range operations on the data. </p>
