title: What does actually minimum_should_match in percentage work for query search?
body: <p>I would to understand more how minimum_should_match works in <strong>elasticsearch</strong> for a a query search </p>
  
  <pre><code>GET /customers/_search
  {
    "query": {
       "bool": {
          "must":[
             {
             "query_string":{
                "query": "大月亮",
                "default_field":"fullName",
                "minimum_should_match": "70%" ------&gt; experimented with this value
             }
          }
        ]
      }
    }
  }
  </code></pre>
  
  <p>I experimented with the percentage in the query and I can see I get different results for Chinese language ?</p>
  
  <p>I tried reading the documentation but did not clearly understand how does this option work ? </p>
