Elasticsearch在index1和index2中删除/更新文档 [英] Elasticsearch delete/update a document in index1 and index2

问题描述

如果我有两个索引，那么Ex：sample1和sample2。
如果我删除或更新sample1中的值，那么相应的文档也应该在sample2中删除或更新？

If I have two index, Ex: sample1 and sample2. If I delete or update a value in sample1 then the corresponding document should also deleted or updated in sample2?

数据：sample1：{name：'Tom' ，id：'1'，city：'xx'，state，'yy'，country：'zz'}
sample2：{id：'1'，city：'xx'，state，'yy'国家：'zz'}
如果我删除id：'1'，那么这个文件应该从服务器端本身的索引中删除。怎么办？
问题将是如果我删除值separatley然后如果我最后在网络问题，从一个索引中删除值后，另一个索引将有值如何避免这个？

Data : sample1 : {name: 'Tom', id: '1', city: 'xx', state, 'yy', country: 'zz'} sample2 : {id: '1', city: 'xx', state, 'yy', country: 'zz'} If I delete id: '1' then this document should be deleted from both the index from the server side itself. How to do this ? The problem will be if I delete the values separatley then if I end up in network issue after deleting value from one index the other index will have values how to avoid this ?

推荐答案

您可以使用批量API ，您将有更好的保证删除/更新操作成功或失败，因为一切都发生在单个网络呼叫中：

You can use the bulk API for doing this and you'll have better guarantees that both delete/update operations succeed or fail since everything happens in a single network call:

要删除两个不同索引的文档：

For deleting both documents in two different indices:

POST _bulk
{"delete": {"_index": "index1", "_type": "type1", "_id": "1"}}
{"delete": {"_index": "index2", "_type": "type2", "_id": "1"}}

要更新两个不同索引的文档： p>

For updating both documents in two different indices:

POST _bulk
{"index": {"_index": "index1", "_type": "type1", "_id": "1"}}
{"name": "Tom", id: "1", "city": "xx", "state": "yy", "country": "zz"}
{"index": {"_index": "index2", "_type": "type2", "_id": "1"}}
{"id": "1", "city": "xx", "state": "yy", "country": "zz"}

更新

这样，似乎需要的解决方案是使用

After discussing this, it seemed the needed solution was a mix of using

• 逐个查询API （不要忘记安装插件，如果你在ES 2。 x）删除与多个索引中的国家匹配的文档


• 和更新查询API ，用于更新多个索引中的文档。

• the delete-by-query API (don't forget to install the plugin if you're on ES 2.x) for deleting documents matching a country in multiple indices
• and the update-by-query API for updating documents in multiple indices.
