elasticsearch - 索引名称中的Elasticsearch日期匹配不起作用

Question

Elasticsearch:2.1

时区:+0800

索引:nginx-2015.12.18

当前时间:2015-12-18 16:08

根据 doc，以下查询将解析为索引 nginx-2015.12.18 curl -XGET 'localhost:9200/<nginx-{now/d}>/_search'
但是，实际上

{"error":{"root_cause":[{"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"<nginx-now","index":"<nginx-now"}],"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"<nginx-now","index":"<nginx-now"},"status":404}

curl'本地主机:9200 / _cat / indices？v'

⋊> ~ curl 'localhost:9200/_cat/indices?v' 16:31:35

事实证明，这是一个known issue，这就是@javanna所说的，

we had initially treated this as a bug and fixed it, but afterwards we found out that the fix introduced a regression (#14177), which made us take a step back. Any slash that should not be used as a path separator in a uri should be properly escaped, and it is wrong to try and make distinctions between the different slashes on the server side depending on what surrounds them, that heuristic is not going to fly (in fact it didn't :) )

We are going to revert the initial fix then, the solution to this problem is to escape the '/' in the url like this: curl -XGET 'localhost:9200/<logstash-{now%2Fd}>/animals/1'. That is going to work and didn't require any fix in the first place.

我还必须转义 {}，这对 ES 2.0有用

curl -XGET 'localhost:9200/<nginx-\{now%2Fd\}>/_search'

这有帮助吗？
