问题 I have created a Elasticsearch cluster with 3 nodes , having 3 shards and 2 replicas. The same query fetch different results when hit to the same index with same data. Right now the results are basically sorted by the _score field desc (I think its the default way of sorting) and requirement also wants that the result be sorted in desc order of there score. So here my question is why does same query yield different result, and then how can this be corrected to have same result every time with

问题 We are going to use CRATE with elasticsearch-cloud-aws plugin for ES to create backups. It looks like current version 0.28.0.1 (from deb package) has an issue with run time environment for aws plugin.

It would be great to have any aws-based backup plugin on board, because it

问题 I have successfully created a query using ElasticSearch's _plugin/head interface. The query is meant to return the latest timestamp for a specific device at a specific location.

问题 I'm using ElasticSearch 2.4.2 (via HibernateSearch 5.7.1.Final from Java). I have a problem with string sorting. The language of my application has diacritics, which have a specific alphabetic ordering. For example Ł goes directly after L , Ó goes after O , etc. So you are supposed to sort the strings like this: Dla Dła Doa Dóa Dza Eza ElasticSearch sorts by typical letters first, and moves all strange letters to at the end: Dla Doa Dza Dła Dóa Eza Can I add a custom letter ordering for

问题 I have an ElasticSearch index with around 200M documents, total index size of 90Gb. I changed mapping, so I would like ElasticSearch to re-index all the documents. I wrote a script that creates a new index (with the new mapping), then goes over all the documents in the old index and puts then into the new one. It seems to work, but the problem is that it works extremely slowly. It started with 300 documents / minute two days ago, and now the speed is 150 documents/minute. The script runs on a
