ElasticSearch查询字符串在嵌套对象中按范围搜索日期 [英] ElasticSearch query string search date by range in nested object
问题描述
假设我的文档具有这种结构
Suppose I have documents that have this kind of structure
{
"_index": "unittest_repositorydb_iscatalogdata_v2",
"_type": "product",
"_id": "Product_100092_In_81810",
"_score": 2.0794415,
"_source": {
"p": {
"effective_dt": null,
"code_s_lower": "B19_9394_Exp",
"expiration_dt": "2020-05-16T00:00:00.0000000Z"
},
"catId_s": "fNXXb5CRkpM"
}
}
我想做的是使用查询字符串按到期日期进行搜索.这是我在Kibana中所做的查询:
What I want to do is search by expiration date using query string. This is the query I do in Kibana:
GET _search
{
"query": {
"query_string": {
"query": "catId_s:fNXXb5CRkpM AND p.expiration_dt:[2020\\-05\\-10T00\\:00\\:00Z TO 2020\\-05\\-17T00\\:00\\:00Z]",
"fields": [
"p.code_s_lower^31",
"p.expiration_dt",
"p.effective_dt"
],
"lenient": true
}
},
"from": 0,
"size": 50,
"_source": [
"catId_s",
"p.code_s_lower",
"p.expiration_dt",
"p.effective_dt"
]
}
但这不会返回任何结果.我发现的一件事是,如果我将日期移到嵌套对象p的外部,并将其与catId_s放在同一级别,则搜索有效.我做错了什么吗?我需要做一些特别的事情来搜索嵌套对象吗?
But this does not return any results. One thing I found was if I move the dates outside the nested object p and putting them at the same level as catId_s, the search was working. Is there any thing I am doing wrong? Do I need to do something special to search in nested objects?
ES的版本为版本:5.3.0,内部版本:3adb13b/2017-03-23T03:31:50.652Z,JVM:1.8.0_231
推荐答案
如果您的经验丰富.dt.的类型为 date
,建议应用适当的范围查询:
If your exp. dt. is of type date
, it's recommended to apply a proper range query:
{
"query":{
"bool":{
"must":[
{
"nested":{
"path":"p",
"query":{
"bool":{
"must":[
{
"range":{
"p.expiration_dt":{
"gte":"2020-05-10T00:00:00Z",
"lte":"2020-05-17T00:00:00Z"
}
}
}
]
}
}
}
}
]
}
}
}
正如@Val所指出的,应将其余的查询字符串拆分并放入嵌套的 must
中.
As @Val pointed out, the rest of your query string should be split and put into the nested must
.
