Elasticsearch中的嵌套查询 [英] Nested query in elasticsearch
问题描述
我无法在使用Elasticsearch的嵌套查询时遇到问题（如果我删除其中一个查询字符串，则可以使用）。我要解决的问题是我有一个包含关闭列表的文档（关闭）。我想在一个条件满足另一个值的闭包列表中搜索一个值。那只是从argan = 1
Im having problem getting a nested query working with elasticsearch (If i remove one of the query-strings it works). the problem I am trying to solve is that i have a document (Closure) containing a list of closures. And I want to search for a value in the list of closures where another value is meet by a condition. That is only take value from a closures where argan=1
{"query":{
"bool":{
"must":[
{
"nested":{
"query":{
"query_string":{
"default_field": "closures.rating",
"query": "5"
},"query_string": {
"default_field": "closure.argang",
"query": "1"
}
},
"path":"closures"
}
}
]
}
}}
我正在收到此错误响应；
Im getting this error-response;

推荐答案
您的查询无效查询。您需要使用适当的复合查询将其他查询组合在一起，不能只使用逗号并添加仅支持一个查询的另一个查询。
Your query is not a valid query. You need to use a proper compound query to combine other queries together, you can't just use a comma and add another query where only one is supported.
您能够 例如，使用布尔查询并具有两个must子句，几乎是您的两个query_string。也许您甚至可以切换到使用过滤器，并进行过滤查询。
我将看一下本文中的示例： http://www.spacevatican.org/2012/6/3/fun-with-elasticsearch-s-children-andnested-documents/ 。
You can for instance use a bool query and have two must clauses, pretty much your two query_string. Or maybe you can even switch to using filters, and have a filtered query. I'd have a look at the examples on this article: http://www.spacevatican.org/2012/6/3/fun-with-elasticsearch-s-children-and-nested-documents/.
