弹性搜索更新映射 [英] Elastic search update mappings

问题描述

我在弹性搜索中为对象错误创建了映射.有没有一种更新映射的方法.对于对象类型(字符串而不是双精度)，错误地创建了映射.

I have mappings created wrongly for an object in elastic search. Is there a way to update the mappings. The mapping has been created wrongly for type of the object(String instead of double).

推荐答案

通常，无法更新现有字段的映射.此规则有一些例外.例如:

In general, the mapping for existing fields cannot be updated. There are some exceptions to this rule. For instance:

new properties can be added to Object datatype fields.
new multi-fields can be added to existing fields.
doc_values can be disabled, but not enabled.
the ignore_above parameter can be updated.
