在弹性搜索中使用现有的字段作为id [英] Use existing field as id in elasticsearch

问题描述

今天刚开始使用elasticSearch。我想知道是否可以设置某种全局参数来使用文档中的某个字段作为ID？

Just started using elasticSearch today. I was wondering if it would be possible to set in some kind of global parameter to use a certain field within a document as the ID always?

我的JSON文档将始终具有它是自己唯一的ID

My JSON documents will always have it's own unique ID

{
  "Record ID": "a06b0000004SWbdAAG",
  "System Modstamp": "01/31/2013T07:46:02.000Z",
  "body": "Test Body"
}

这里我想使用记录ID作为ID字段。

Here I would like to use Record ID as the ID field.

注意

推荐答案

要使用路径设置，请参阅这里的文档：

You want to use the path setting, see the docs here:

http://www.elasticsearch.org/guide/reference/mapping/id-field/

具体而言应该在你的映射中工作：

specifically something like this should work in your mapping:

{
    "your_mapping" : {
        "_id" : {
            "path" : "Record ID"
        }
    }
}

我从来没有尝试过将变量名称分解。如果你遇到懦弱，你可能想要骆驼或下划线。

I've never tried having variable names split up though. You might want to camelcase or underscore them if you run into wierdness.
