在Elasticsearch查询中包含和排除索引 [英] Including and excluding indexes in Elasticsearch query

问题描述

我有以下Elasticsearch查询。

I have the following Elasticsearch query.

GET /index1,index2/type1,type2/_search?q=programming

假设我要从 index2 中排除此搜索查询。 文档指出以下内容 ：

Let's say that I want to exclude index2 from this search query. The documentation states the following:

它还支持通配符，例如：test *，以及
的功能添加（+）和删除（-），例如：+ test *，-test3。

It also support wildcards, for example: test*, and the ability to "add" (+) and "remove" (-), for example: +test*,-test3.

据我所知，我应该能够请执行以下操作。

As far as I understand, I should be able to do the following.

GET /+index1,-index2/type1,type2/_search?q=programming

但是，出现以下错误。

{
  "error": {
    "root_cause": [
      {
        "type": "index_not_found_exception",
        "reason": "no such index",
        "resource.type": "index_or_alias",
        "resource.id": " index1",
        "index": " index1"
      }
    ],
    "type": "index_not_found_exception",
    "reason": "no such index",
    "resource.type": "index_or_alias",
    "resource.id": " index1",
    "index": " index1"
  },
  "status": 404
}

如果删除加号和减号，则查询运行正常。如果我添加通配符，它​​似乎可以工作，例如

If I remove the plus and minus signs, the query runs fine. If I add a wildcard, it seems to work, e.g. the below query.

GET /index1,-*index2/type1,type2/_search?q=programming

但是，这并不是我真正想要的。

However, that's not really what I want.

为什么当文档中使用加号和减号包括或排除索引时，我的查询不起作用？我误会了吗？

Why is my query not working when I use plus and minus signs to include or exclude indexes as the documentation states? Am I misunderstanding something?

我正在使用Elasticsearch 2.1。

I am using Elasticsearch 2.1.

推荐答案

您需要编码 + 符号，因为它在URL字符串中被视为空格。看到在 resource.id： index1，

You need to encode the + sign as it is considered space in URL string. See there is space in "resource.id": " index1",

这将起作用

GET /%2Bindex1,-index2/type1,type2/_search?q=programming

希望这会有所帮助！
