elasticsearch - Elasticsearch索引映射更新

Question

我正在使用ES-2.4.0
索引json:
{
"_id": 1,
"name": "Longsword",
"description": "The Longsword can be wielded in one or two hands",
"category": "Sharp"
}
1.我创建了一个索引，并且正在创建默认映射。
2.现在，我正在尝试按照此处的建议更新映射。

连结:https://gist.github.com/nicolashery/6317643

关于点1:我没有使用过任何分析仪；
关于点2:我正在使用分析器“not_analysed”；

但这是行不通的。

问题:如果没有，ES-2.X是否停止了映射更新工具，我该如何更新映射？

注意:尝试时出现此错误

{ "error": { "root_cause": [ { "type": "illegal_argument_exception", "reason": "Mapper for [name] conflicts with existing mapping in other types:\n[mapper [name] has different [analyzer]]" } ], "type": "illegal_argument_exception", "reason": "Mapper for [name] conflicts with existing mapping in other types:\n[mapper [name] has different [analyzer]]" }, "status": 400 }

Answer 1

否，从 ES 2.x 开始，不允许更改现有字段的映射类型。

从documentation

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.

您必须首先 delete the index并使用新映射创建一个新的。还有一个小错字，是 not_analyzed (“z”不是“s”)
