I have example data as below, But I need to aggregate teams and players with multiple nested fields ("foot-ball-teams", "cricket-teams").

I have to get output unique teams from "foot-ball-teams", "cricket-teams" and unique team's players of each team

```
PUT /sports/
{
  "mappings": {
    "_doc": {
      "properties": {
        "foot-ball-teams": {
          "type": "nested",
          "properties": {
            "name": {
              "type": "keyword"
            },
            "players": {
              "type": "keyword"
            }
          }
        },
        "cricket-teams": {
          "type": "nested",
          "properties": {
            "name": {
              "type": "keyword"
            },
            "players": {
              "type": "keyword"
            }
          }
        }
      }
    }
  }
}

POST /sports/_doc
{

    "foot-ball-teams": [
        { "name": "team1",
          "players": [
              "player1",
              "player2"
          ]  
        },
        { "name": "team2",
            "players": [
                "player1",
                "player3"
            ]
          }
    ],

    "cricket-teams": [
        { "name": "team1",
          "players": [
              "player1",
              "player2"
          ]  
        },
        { "name": "team2",
            "players": [
                "player1",
                "player4"
            ]
          }
    ]
}
```

Are you sure the mapping you provided is correct? The players field is defined as a keyword but you are indexing an array of values.

Yes its working fine, Array of words will be treated as keywords.
