如果别名是精确到某天的话，那就需要每天来更新别名了吧？有没有方式让它默认一直是当天索引的别名？

#Index Alias 经测试，可以对不同的索引起相同的别名 DELETE /titles DELETE /titles2 PUT /titles { "mappings": { "properties": { "title": { "type": "text", "analyzer": "english", "fields": {"std": {"type": "text","analyzer": "standard"}} } } } } PUT /titles2 { "mappings": { "properties": { "title": { "type": "text", "analyzer": "english", "fields": {"std": {"type": "text","analyzer": "standard"}} } } } } POST titles/_bulk { "index": { "_id": 1 }} { "title": "My dog barks" } { "index": { "_id": 2 }} { "title": "I see a lot of barking dogs on the road " } POST titles2/_bulk { "index": { "_id": 3 }} { "title": "My dog barks" } { "index": { "_id": 4 }} { "title": "I see a lot of barking dogs on the road " } POST _aliases { "actions": [ { "add": { "index": "titles", "alias": "aliastitle" } } ] } POST _aliases { "actions": [ { "add": { "index": "titles2", "alias": "aliastitle" } } ] } GET /aliastitle/_search { "query": { "multi_match": { "query": "barking dogs", "type": "most_fields", "fields": [ "title", "title.std" ] } } } GET /aliastitle/_search { "query": { "multi_match": { "query": "barking dogs", "type": "most_fields", "fields": [ "title^10", "title.std" ] } } }

老师您好，请教下您举例这个 "id":"tmdb",这个是什么意思，必须指定吗？ POST _scripts/tmdb { "script": { "lang": "mustache", "source": { "_source": [ "title","overview" ], "size": 20, "query": { "multi_match": { "query": "{{q}}", "fields": ["title","overview"] } } } } } POST tmdb/_search/template { "id":"tmdb", "params": { "q": "basketball with cartoon aliens" } }

这一节太有用了

别名是不是类似于SQL里的视图？

创建索引模板，并设置了mapping ，往索引中写入数据后没有异常但索引中找不到写入的文档这种问题怎么处理？

老师，代码演示在github上给的不全，aliases相关部分没有

两个索引的别名可以一样吗？

不停机运维没讲啊
