我的文档是像下面的格式，我没有做任何Map，但它出来不同，当我使用两个字段来执行顶部命中聚合

"max_score": 1.0,
    "hits": [
        {
            "_index": "data",
            "_type": "test",
            "_id": "UzzwY3cBOTCkvi7mN2VG",
            "_score": 1.0,
            "_source": {
                "hdId": 20210120,
                "hrId": 5348,
                "timestamp": 1612289417551,
                "timestampstring": "2021-02-03 02:10:17.551",
                "ooId": "672848824",
                "okCount": 17,
                "totalVol": 4220842,
                "type": "test"
            }
        }
    ]

我想使用“Top Hit”聚合来找出我查询的每个ID的最新记录，

{
"query": {
    "bool": {
    "must": {
        "terms": {
        "ooId": [672848824,672848823]
        }
    },
    
    "filter": {
        "match": {
        "type": "test"
        }
    }
    }
},
"size": 1,
"aggs": {
    "unique_id": {
    "terms": {
        "field": "ooId",
        "size": 1
    },
    "aggs": {
        "top_result": {
        "top_hits": {
            "size": 1,
            "_source": ["ooId","totalVol","okCount"],
            "sort": {
            "timestamp" : "desc"
            }
        }
        }
    }
    }
}
}

when i do the about query, it shows the ERROR
{
    "error": {
        "root_cause": [
            {
                "type": "illegal_argument_exception",
                "reason": "Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default.

            }
        ],
        "type": "search_phase_execution_exception",
        "reason": "all shards failed",
        "phase": "query",
        "grouped": true,
        "failed_shards": [
            {
                "shard": 0,
                "index": "test",
                "node": "CzM0ERKGTVyQc3mSiRBY2A",
                "reason": {
                    "type": "illegal_argument_exception",
                    "reason": "Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default.

                }
            }
        ],
        "caused_by": {
            "type": "illegal_argument_exception",
            "reason": "Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default.

            "caused_by": {
                "type": "illegal_argument_exception",
                "reason": "Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default.

            }
        }
    },
    "status": 400
}

但当我使用另一个字段“hdId”取代“ooId“做查询它去没有错误
像`

"aggs": {
    "unique_id": {
    "terms": {
        "field": "hdId",
        "size": 1
    },

出来的时候没问题

                }
            }

}
我怎么能修复错误，因为我不想使用hdId作为查询参数，
谢谢
