在function_score上期待另一个结果（得分）

Question

我想知道查询的得分。我在文档的权重字段上使用了sudo apic status。如果我搜索“ wien”一词，则两个文档来自两个索引。

这是我的查询：

function_score

另一方面，我的结果：

GET _all/_search
{
 "query": {
  "function_score" : {
    "query" : {
      "bool" : {

我不明白为什么"hits": [ { "_index": "city", "_type": "city", "_id": "589", "_score": 377704.28, "_source": { "svno": 589, "city": { "name": "Wien", "name_de": "Wien", "name_it": "Vienna", "name_fr": "Vienne", "name_hu": "Bécs", "name_cs": "Vídeň" }, "regions": [ { "name": "Wien", "name_de": "Wien", "name_it": "Vienne", "name_fr": "Vienna", "name_hu": "Bécs", "name_cs": "Vídeň" } ], "nation": { "name": "Österreich", "name_de": "Österreich", "name_it": "Austria", "name_fr": "Autriche", "name_hu": "Ausztria", "name_cs": "Rakousko" }, "location": { "lat": 48.20827865600586, "lon": 16.373079299926758 }, "weight": 32300 } }, { "_index": "servicename", "_type": "servicename", "_id": "593", "_score": 279269.25, "_source": { "id": "593", "servicename": { "name": "Wien", "name_de": "Wien", "name_it": "Vienne", "name_fr": "Vienna", "name_hu": "Bécs", "name_cs": "Vídeň" }, "city": null, "region": { "svno": 593, "regions": [ { "name": "Wien", "name_de": "Wien", "name_it": "Vienne", "name_fr": "Vienna", "name_hu": "Bécs", "name_cs": "Vídeň" } ], "nation": { "name": "Österreich", "name_de": "Österreich", "name_it": "Austria", "name_fr": "Autriche", "name_hu": "Ausztria", "name_cs": "Rakousko" } }, "theme": null, "contract": null, "enabled": true, "weight": 35300 } } ] 索引的结果比city索引的结果高。 servicename的权重为servicename，35300的权重为city。

我希望32300文档应该是最好的结果。

您对此有何解释？
