问题
当我按一个特定的方面过滤时,该特定字段的方面在结果中被正确过滤,但是其他方面字段保持不变。最好的解释方法是查询和响应。
查询
{
query: {
match_all: {}
},
filter: {
and: [{
term: {
"address.state": "oregon"
}
}]
},
facets: {
"address.city": {
terms: {
field: "address.city"
},
facet_filter: {}
},
"address.state": {
terms: {
field: "address.state"
},
facet_filter: {
and: [{
term: {
"address.state": "oregon"
}
}]
}
},
"address.country": {
terms: {
field: "address.country"
},
facet_filter: {}
}
}
}
结果
{
"took": 2,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1,
"hits": [
{
"_index": "races",
"_type": "race",
"_id": "6",
"_score": 1,
"_source": {
"id": 6,
"name": "Eugene Marathon",
"description": "...",
"created_at": "2015-05-24T19:41:45.043Z",
"updated_at": "2015-05-24T19:41:45.046Z",
"address": {
"race_id": 6,
"id": 7,
"line1": null,
"line2": null,
"city": "Eugene",
"state": "oregon",
"country": "united_states",
"zip": null,
"user_id": null,
"created_at": "2015-05-24T19:41:45.044Z",
"updated_at": "2015-05-24T19:41:45.044Z"
},
"race_years": []
}
}
]
},
"facets": {
"address.city": {
"_type": "terms",
"missing": 0,
"total": 7,
"other": 0,
"terms": [
{
"term": "long beach",
"count": 1
},
{
"term": "lincoln",
"count": 1
},
{
"term": "las vegas",
"count": 1
},
{
"term": "jackson",
"count": 1
},
{
"term": "eugene",
"count": 1
},
{
"term": "duluth",
"count": 1
},
{
"term": "denver",
"count": 1
}
]
},
"address.state": {
"_type": "terms",
"missing": 0,
"total": 1,
"other": 0,
"terms": [
{
"term": "oregon",
"count": 1
}
]
},
"address.country": {
"_type": "terms",
"missing": 0,
"total": 7,
"other": 0,
"terms": [
{
"term": "united_states",
"count": 7
}
]
}
}
}
所以你可以看到它返回所有 address.city
面,即使唯一的结果是在尤金。它还返回了7的数字 united_states
. 为什么它会返回所有这些额外的方面和不正确的计数?我的rubyMap可以在下面找到。
rubyMap
settings index: {
number_of_shards: 1,
analysis: {
analyzer: {
facet_analyzer: {
type: 'custom',
tokenizer: 'keyword',
filter: ['lowercase', 'trim']
}
}
}
} do
mapping do
indexes :name, type: 'string', analyzer: 'english', boost: 10
indexes :description, type: 'string', analyzer: 'english'
indexes :address do
indexes :city, type: 'string', analyzer: 'facet_analyzer'
indexes :state, type: 'string'
indexes :country, type: 'string'
end
end
end

这是面在过滤器上运行时的正常行为。根据官方文件:
有一个重要的区别要记住。虽然搜索查询同时限制返回的文档和方面计数,但搜索筛选器只限制返回的文档,而不限制方面计数。
在您的例子中,您的查询匹配所有文档(即。
match_all
)因此,facet计数也被计算在所有文档中。将查询更改为this,facet计数将更改(在这种情况下,您不需要
facet_filter
不再):另一件值得注意的事情是facet已经被弃用,并被更强大的聚合所取代。
