我正在尝试在嵌套 ES 查询上应用位置半径，但嵌套值并非一直存在导致异常
"[nested] nested object under path [contact.address] is not of nested type"
我试图检查该属性是否存在然后应用过滤器但到目前为止没有任何效果
映射如下:
{
"records": {
"mappings": {
"user": {
"properties": {
"user_id": {
"type": "long"
},
"contact": {
"properties": {
"address": {
"properties": {
"city": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"location": {
"properties": {
"lat": {
"type": "long"
},
"lng": {
"type": "long"
},
"lon": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
}
},
"email": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"name": {
"properties": {
"first_name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"last_name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
}
}
},
"created_at": {
"type": "date"
}
}
}
}
}
}
有时记录没有位置或地址数据，这会导致问题。样本记录:
{
"contact": {
"name": {
"first_name": "Test",
"last_name": "User"
},
"email": "test@user.com",
"address": {}
},
"user_id": 532188
}
这是我正在尝试的:
GET records/_search
{
"query": {
"bool": {
"must": [
{
"exists": {
"field": "contact.address"
}
},
{
"exists": {
"field": "contact.address.location"
}
}
],
"minimum_should_match": 1,
"should": [
{
"bool": {
"filter": {
"nested": {
"ignore_unmapped": true,
"path": "contact.address",
"query": {
"geo_distance": {
"distance": "50mi",
"contact.address.location": {
"lat": 51.5073509,
"lon": -0.1277583
}
}
}
}
}
}
}
]
}
}
}
最佳答案
您需要使用 nested 数据类型定义正确的映射以避免此问题，看起来动态映射正在产生一些问题。
我用 nested 数据类型定义了我自己的映射，即使我错过了嵌套字段中的一些数据，它也不会提示。
索引定义
{
"mappings": {
"properties": {
"user_id": {
"type": "long"
},
"contact": {
"type": "nested"
}
}
}
}
索引示例文档
{
"contact": {
"name": {
"first_name": "raza",
"last_name": "ahmed"
},
"email": "opster@user.com",
"address" :{ --> note empty nested field
}
},
"user_id": 123456
}
用嵌套字段中的数据索引另一个文档
{
"contact": {
"name": {
"first_name": "foo",
"last_name": "bar"
},
"email": "opster@user.com",
"address": {
"location" :{. --> note nested data as well
"lat" : 51.5073509,
"lon" : -0.1277583
}
}
},
"user_id": 123456
}
索引另一个文档，它甚至没有空的
nested 数据{
"contact": {
"name": {
"first_name": "foo",
"last_name": "bar"
},
"email": "opster@user.com"
},
"user_id": 123456
}
使用
nested 字段搜索查询{
"query": {
"nested": {
"path": "contact", --> note this
"query": {
"bool": {
"must": [
{
"exists": {
"field": "contact.address"
}
},
{
"exists": {
"field": "contact.name.first_name"
}
}
]
}
}
}
}
}
搜索结果不会提示不包含嵌套文档的文档(给您带来问题的查询)
"hits": [
{
"_index": "nested",
"_type": "_doc",
"_id": "3",
"_score": 2.0,
"_source": {
"contact": {
"name": {
"first_name": "foo",
"last_name": "bar"
},
"email": "opster@user.com",
"address": { --> note the nested doc
"location": {
"lat": 51.5073509,
"lon": -0.1277583
}
}
},
"user_id": 123456
}
}
