title: How to boost individual words in a elasticsearch match query
body: <p>Suppose I want to query "Best holiday places to visit during summer" in a Elasticsearch cluster. But I want holiday, visit and summer to have high priority than other words:</p>
  
  <p>Something Like this: Best holiday^4 places to visit^3 during summer^2.</p>
  
  <p>I know about field boosting but what I want to do is not achievable by boost. 
  Basically I want to boost individual words.</p>
  
  <p>Does any one have any idea about doing this in Elasticsearch 5.6 above??</p>
