title: Is there any analyzer that performs exact word matching in elastic search
body: <p>Is there any analyzer that performs exact word matching in elastic search</p>
  
  <p>Example if, i have words like "America" and "American" and "America's", if i searched for "America" i should get only first one.. With standard analyzer it gives all the three ones. </p>
  
  <p>I want to make sure this only at query time. I don't want to make changes to existing index. Please help me. </p>
