title: Applying match_phrase and filter
body: <p>Worked on Elastic Search 6.4.2. I want to use <code>match_pharse</code>to get the retrieve the results from my index. In the same way I need to apply the filter for that. Any solution for this. I tried the below query   </p>
  
  <pre><code>{
    "query": {
      "bool": {
        "should": 
          {
            "match_phrase": {
            "title": "bike riding"
            }}
  
      }
    }}
  </code></pre>
  
  <p>But When I using <code>match_pharse</code> I need to pass the fields  in order to get the results. I am sharing my mapping  and query that I need to be edited. Any help that I can use the <code>match_phrase</code> for a query.  </p>
