你在创建索引，指定索引mapping时，需要将该字段指定为"type": "nested"类型，如："petList": {
        "type": "nested",
        "properties": {
          "birthday": {
            "type": "date"
          },
          "breedId": {
            "type": "long"
          },
          "breedName": {
            "type": "text"
          },
          "gender": {
            "type": "text"
          },
          "id": {
            "type": "long"
          },
          "imgUrl": {
            "type": "text"
          },
          "name": {
            "type": "text",
            "analyzer": "ik_max_word"
          }
        }
      },

根据此嵌套对象中字段name查询时，使用

QueryBuilders.nestedQuery("petList", QueryBuilders.matchQuery("petList.name", query), ScoreMode.Total)构建QueryBuilder对象进行查询。
