[darshan_ambre]

How to return only exact match if exists else perform wildcard search. for e.g. for the below given set of data

    [
      {
        "_index" : "priority_test",
        "_type" : "_doc",
        "_id" : "3IkeZHUBYJCjRlSv-EXV",
        "_score" : 1.0,
        "_source" : {
          "number" : "GI#000001",
          "name" : "GI for Cost Center",
          "comments" : "Cost Center",
          "id" : "000001",
          "PlantCode" : "ABC"
        }
      },
      {
        "_index" : "priority_test",
        "_type" : "_doc",
        "_id" : "3YkeZHUBYJCjRlSv-EXV",
        "_score" : 1.0,
        "_source" : {
          "number" : "GI#0000010",
          "name" : "GI for WBS Element",
          "comments" : "WBS Element",
          "id" : "0000010",
          "PlantCode" : "XYZ"
        }
      },
      {
        "_index" : "priority_test",
        "_type" : "_doc",
        "_id" : "3okeZHUBYJCjRlSv-EXV",
        "_score" : 1.0,
        "_source" : {
          "number" : "GI#0000011",
          "name" : "GI for Cost Center & WBS Element",
          "comments" : "Cost Center & WBS Element",
          "id" : "0000011",
          "PlantCode" : "LMN"
        }
      },
      {
        "_index" : "priority_test",
        "_type" : "_doc",
        "_id" : "4IkeZHUBYJCjRlSv-EXV",
        "_score" : 1.0,
        "_source" : {
          "number" : "GI#00000100",
          "name" : "Manage Pick List GI",
          "comments" : "Manage Pick List GI",
          "id" : "00000100",
          "PlantCode" : "QRS"
        }
      }
    ]

In the above data, If i search for "GI#000001" in document number, The result must return only that document, otherwise it should perform a contains search that starts with "GI#000001*".

I've formed a query with looks something like the following:

    {
  "query": {
    "bool": {
      "should": [
        {
          "terms": {
            "number.keyword": [
              "GI#000001"
            ]
          }
        },
        {
          "query_string": {
            "fields": [
              "number.keyword"
            ],
            "query": """GI\#000001*"""
          }
        }
      ]
    }
  }
}

But the above query always returns a result even if there is an exact match available for "GI#000001".

Please guide me in building this search
