SQL like GROUP BY AND HAVING

由 萝らか妹 提交于 2019-11-28 18:55:52
I want to get the counts of groups which satisfy a certain condition. In SQL terms, I want to do the following in Elasticsearch.

Word-oriented completion suggester (ElasticSearch 5.x)

由 与世无争的帅哥 提交于 2019-11-27 01:07:10
问题 ElasticSearch 5.x introduced some (breaking) changes to the Suggester API (Documentation). Most notable change is the following: Completion suggester is document-oriented Suggestions are aware of the document they belong to. Now, associated documents ( _source ) are returned as part of completion suggestions. In short, all completion queries return all matching documents instead of just matched words . And herein lies the problem - duplication of autocompleted words if they occur in more than
