1. 查看索引类型结构
为了查看索引的类型结构,可以执行以下命令: `GET /my_index/_mapping` 返回结果: ```json { "my_index": { "mappings": { "_meta": {}, "_source": { "includes": [], "excludes": [] }, "numeric_detection": false, "properties": { "my_field": { "type": "text" } } } } } ```
2. 添加Keyword类型
为了添加Keyword类型,可以执行以下 PUT 请求: `PUT /my_index/_mapping` 请求体: ```json { "properties": { "my_field": { "type": "text", "fields": { "keyword": { "type": "keyword", "ignore_above": 256 } } } } } ``` 返回结果: ```json { "acknowledged": true } ```
