Delete documents of type in Elasticsearch

Question

I want to delete all the documents indexed within a type in Elasticsearch, using the HTTP/REST api, but I don\'t want to delete the mapping for this type

How can I build

Answer 1

With the following command in the elasticsearch head plugin I was able to delete all documents of type logs from the logstash index without deleting the mapping:

{"query":{"match_all":{}}}

To free space on the disk you must also optimize the index (Actions->Optimize for index logstash in the head plugin) after deleting the documents.
