我使用elasticesearch來搜索城市信息，當我搜索省，我想要得到屬於這個省的城市列表。我搜索了很多關於如何搜索和分類存儲桶的答案，如aggs, script，而此解決方案只能按原始文檔中的字段進行排序。Elasticsearch如何基於sammple結果的排序桶max_score
我希望通過抽樣結果的max_score，這裏是我的查詢排序：
GET /config/city/_search?
{
"query":
{
"match":{
"province":"湖北"
}
},
"aggs": {
"city": {
"terms": {
"field": "city_name.keyword",
"order":{
"_term": "desc"
}
},
"aggs": {
"sample": {
"top_hits": {
"size": 1
}
}
}
}
}
}
查詢和AGGS結果是：
