如何用弹性搜索中的数组元素进行搜索？ [英] How to search by array elements in elasticsearch?

问题描述

  {
content：Some content with @someone提到，
提到：[某人]，
userId：4dff31eaf8815f4df04e2d62
}  

我尝试用查询找到它：

  {
query： {
filtered：{
filter：{term：{userId：4dff31eaf8815f4df04e2d62}}，
query：{
 term：{ 提到：某人} 
} 
} 
} 
}  

同时内容查询工作正常：

  {
query：{
filtered：{
filter：{term：{userId：4dff31eaf8815f4df04e2d62}} 
query：{
term：{content：some} 
} 
} 
} 
}  

是一些specia l通过数组搜索所需的语法？我发现了几个主题[ 1 ，<关于弹性搜索中的数组的href =http://elasticsearch-users.115913.n3.nabble.com/Query-Syntax-for-arrays-and-nested-objects-td212582.html> 2 ]但是没有直接的答案。

UPD 获取Mapping调用返回下一个结果：

  {
records：{
all：{
properties：{
content：{类型：string}，
userId：{type：string}，
提到：{type：string} 
} 
} 
} 
}  

UPD2 的问题。我不小心在我的问题中引入了一个错误。 DB中实际使用的用户名是some_one（下划线是重要的）。因此，标准索引将其分为2个字，并查询原因失败的some_one。

解决方案

这是正确的用法，更新提示。

如果您导入带有提及数组的文档，则在匹配的数组项上进行搜索，将其称为提及，将检索该文档。我有同样的问题，现在就自己验证了。

I have a document indexed in elasticsearch:

{
    "content":"Some content with @someone mention",
    "mentions":["someone"],
    "userId":"4dff31eaf8815f4df04e2d62"
}

I try to find it with a query:

{
    "query": {
        "filtered": {
            "filter": { "term":{"userId":"4dff31eaf8815f4df04e2d62"} },
            "query": {
                term: {"mentions":"someone"}
            }
        }
    }
}

and receive no results.

In the same time query for content works fine:

{
    "query": {
        "filtered": {
            "filter": { "term":{"userId":"4dff31eaf8815f4df04e2d62"} },
            "query": {
                "term": {"content":"some"}
            }
        }
    }
}

Is some special syntax required for search through arrays? I found several topics [1, 2] about arrays in elasticsearch, but there is no direct answer.

UPD Get Mapping call returns the next result:

{
    "records": {
        "all":{
            "properties":{
                "content":{"type":"string"},
                "userId":{"type":"string"},
                "mentions":{"type":"string"}
            }
        }
    }
}

UPD2 I found the source of problem. I accidentally introduced an error into my question. The username I actually had in DB was in form "some_one" (underscore is significant). So standard index split it into 2 words and query for "some_one" of cause failing.

解决方案

This is correct usage, as your update mentions.

If you import a document with a "mentions" array, searching on a matching array item, referring to it as "mentions", will retrieve the document. I had the same issue and verified it myself just now.
