如何解决如何解决 Elastic Search 中的 Top hit ERROR？

开发过程中遇到如何解决 Elastic Search 中的 Top hit ERROR的问题如何解决？下面主要结合日常开发的经验，给出你关于如何解决 Elastic Search 中的 Top hit ERROR的解决方法建议，希望对你解决如何解决 Elastic Search 中的 Top hit ERROR有所启发或帮助；

我的文档类似于以下格式，我没有做任何映射，但是当我使用两个字段来执行热门聚合时，结果会有所不同

 "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,"@R_835_10586@lVol": 4220842,"type": "test"
            }
        }
    ]

我想使用“热门”聚合来找出每个 ID 的最新记录我的查询就像

{
"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","@R_835_10586@lVol","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. Please use a keyword fIEld instead. Alternatively,set fIElddata=true on [ooID] in order to load fIEld data by uninverTing the inverted index. Note that this can use significant memory."
            }
        ],"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",set fIElddata=true on [ooID] in order to load fIEld data by uninverTing the inverted index. Note that this can use significant memory."
                }
            }
        ],"caused_by": {
            "type": "illegal_argument_exception",set fIElddata=true on [ooID] in order to load fIEld data by uninverTing the inverted index. Note that this can use significant memory.","caused_by": {
                "type": "illegal_argument_exception",set fIElddata=true on [ooID] in order to load fIEld data by uninverTing the inverted index. Note that this can use significant memory."
            }
        }
    },"status": 400
}

但是当我使用另一个字段“hdID”代替“ooID”进行查询时，它不会出错

喜欢`

"aggs": {
    "unique_ID": {
    "terms": {
        "fIEld": "hdID",

结果没问题
