PUT /my-index-000001{ "mappings": { "properties": { "user_id": { "type": "keyword", "ignore_above": 20 } } }}PUT /my-index-000001/_mapping{ "properties": { "user_id": { "type": "keyword", "ignore_above": 100 } }}在已存在的字段中批改映射
除了批改反对的映射参数外，不能批改已有的字段映射或字段类型。更改已有字段可能会使曾经建设索引的数据有效。
如果须要批改索引中字段的映射，能够应用新的映射创立一个新索引，而后将数据从新索引到该索引中。
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
重命名字段会使在旧字段名称下已建设索引的数据生效。取而代之的是，增加一个别名字段作为字段名称。
