看起来您构建嵌套过滤器的方式不正确。您在这里列出的内容也不适合我。
但是当我替换这个：
"sort": [
{
"children.size": {
"order": "asc",
"nested_filter": {
"nested": {
"filter": {
"term": {
"id": 1
}
},
"path": "children"
}
}
}
}
]
有了这个：
"sort": [
{
"children.size": {
"order": "desc",
"nested_filter": {
"term": {
"id": 1
}
}
}
}
]
有效。
更准确地说，我建立了索引并添加了数据：
DELETE /test_index
PUT /test_index/
{
"settings": {
"number_of_shards": 1,
"number_of_replicas": 0
}
}
PUT /test_index/item/_mapping
{
"item": {
"properties": {
"name": {
"type": "string",
"store": "yes"
},
"children": {
"properties": {
"name": {
"type": "string",
"store": "yes"
},
"id": {
"type": "integer",
"store": "yes"
},
"size": {
"type": "integer",
"store": "yes"
}
},
"type": "nested"
}
}
}
}
PUT /test_index/item/1
{"name":"item1","children":[{"id":11,"size":15},{"id":3,"size":6}]}
PUT /test_index/item/2
{"name":"item2","children":[{"id":1,"size":2},{"id":3,"size":6}]}
PUT /test_index/item/3
{"name":"item3","children":[{"id":1,"size":7},{"id":3,"size":36}]}
PUT /test_index/item/4
{"name":"item4","children":[{"id":1,"size":11},{"id":3,"size":16}]}
然后使用进行搜索，如下所示，"order": "desc"它似乎可以正常运行：
POST /test_index/item/_search
{
"query": {
"filtered": {
"query": {
"match_all": {}
},
"filter": {
"nested": {
"filter": {
"term": {
"id": 1
}
},
"path": "children"
}
}
}
},
"sort": [
{
"children.size": {
"order": "desc",
"mode": "avg",
"nested_filter": {
"term": {
"id": 1
}
}
}
}
]
}
...
{
"took": 2,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"Failed": 0
},
"hits": {
"total": 3,
"max_score": null,
"hits": [
{
"_index": "test_index",
"_type": "item",
"_id": "4",
"_score": null,
"_source": {
"name": "item4",
"children": [
{
"id": 1,
"size": 11
},
{
"id": 3,
"size": 16
}
]
},
"sort": [
11
]
},
{
"_index": "test_index",
"_type": "item",
"_id": "3",
"_score": null,
"_source": {
"name": "item3",
"children": [
{
"id": 1,
"size": 7
},
{
"id": 3,
"size": 36
}
]
},
"sort": [
7
]
},
{
"_index": "test_index",
"_type": "item",
"_id": "2",
"_score": null,
"_source": {
"name": "item2",
"children": [
{
"id": 1,
"size": 2
},
{
"id": 3,
"size": 6
}
]
},
"sort": [
2
]
}
]
}
}
