弹性搜索中存储的字段 [英] Stored field in elastic search

问题描述

在文档中，某些类型，如数字和日期，它指定该商店默认为no。但是，该字段仍然可以从json检索。

In the documentation, some types, such as numbers and dates, it specifies that store defaults to no. But that the field can still be retrieved from the json.

它的混乱。这是否意味着_source？

Its confusing. Does this mean _source?

有没有办法不存储一个字段，只需要索引和可搜索？

Is there a way to not store a field at all, and just have it indexed and searchable?

推荐答案

默认情况下，不存储任何字段类型。只有 _source 字段是。这意味着您可以随时收回您发送到搜索引擎的内容。即使您要求具体字段，弹性搜索将会为您解析 _source 字段，并返回这些字段。

None of the field types are stored by default. Only the _source field is. That means you can always get back what you sent to the search engine. Even if you ask for specific fields, elasticsearch is going to parse the _source field for you and give you back those fields.

如果你想要的话，你可以禁用 _source ，然后根据你的映射，你只能检索你显式存储的字段。

You can disable the _source if you want but then you could only retrieve the fields that you explicitly stored, according to your mapping.
