除了修改支持的映射参数外,不能修改已有的字段映射或字段类型。更改已有字段可能会使已经创建索引的数据无效。app
若是须要修改索引中字段的映射,能够使用新的映射建立一个新索引,而后将数据从新索引到该索引中。ide
PUT /my-index-000001 { "mappings" : { "properties": { "user_id": { "type": "long" } } } } POST /my-index-000001/_doc?refresh=wait_for { "user_id" : 12345 } POST /my-index-000001/_doc?refresh=wait_for { "user_id" : 12346 } PUT /my-new-index-000001 { "mappings" : { "properties": { "user_id": { "type": "keyword" } } } } # 复制文档 POST /_reindex { "source": { "index": "my-index-000001" }, "dest": { "index": "my-new-index-000001" } }
重命名字段会使在旧字段名称下已创建索引的数据失效。取而代之的是,添加一个别名字段做为字段名称。code
