Answer 1

Adding a working example with index data, mapping,search query, and search result.

You need to use nested query to search on nested fields

Index Mapping

{
    "mappings": {
        "properties": {
            "citedIn": {
                "type": "nested"
            }
        }
    }
}

Index Data:

 {
        "citedIn": [
            {
                "someFiled": "Bar Councils Act, 1926 - Section 15"
            },
            {
                "someFiled": "Contract Act, 1872 - Section 23"
            }
        ]
    }
    {
        "citedIn": [
            {
                "someFiled": "15 C. B 400"
            },
            {
                "someFiled": "Contract Act, 1872 - Section 55"
            }
        ]
    }
    {
        "citedIn": [
            {
                "someFiled": "15 C. B 400"
            },
            {
                "someFiled": "Contract Act, 1872 - Section 15"
            }
        ]
    }

Search Query:

{
    "query": {
        "nested": {
            "path": "citedIn",
            "query": {
                "bool": {
                    "must": [
                        {
                            "match": {
                                "citedIn.someFiled": "contract"
                            }
                        },
                        {
                            "match": {
                                "citedIn.someFiled": "act"
                            }
                        },
                        {
                            "match": {
                                "citedIn.someFiled": 15
                            }
                        }
                    ]
                }
            },
            "inner_hits": {}
        }
    }
}

Search Result:

"inner_hits": {
          "citedIn": {
            "hits": {
              "total": {
                "value": 1,
                "relation": "eq"
              },
              "max_score": 1.620718,
              "hits": [
                {
                  "_index": "stof_64170705",
                  "_type": "_doc",
                  "_id": "3",
                  "_nested": {
                    "field": "citedIn",
                    "offset": 1
                  },
                  "_score": 1.620718,
                  "_source": {
                    "someFiled": "Contract Act, 1872 - Section 15"
                  }
                }
              ]
            }
          }
        }
      }
