                }
              }
            } ],
            "minimum_should_match" : "1"
          }
        }, {
          "match" : {
            "skills" : {
              "query" : "c#",
              "type" : "phrase",
               "analyzer" : "synonym"


            }
          }
        } ]
      }
       }
    }

Result is coming when i replace c# with other skill like java. But if c# or .net is mentioned in search query it is result is comin blank even those skills are already indexed.

            }
         }
      ]
   }
}

Content section i have removed because of max character allowed. You can see that c# is indexed in document but still not able to get the result.
