Delete all documents from index/type without deleting type

Question

I know one can delete all documents from a certain type via deleteByQuery.

Example:

curl -XDELETE \'http://localhost:9200/twitter/tweet/_query\' -d \         


        

Answer 1

You can delete documents from type with following query:

POST /index/type/_delete_by_query
{
    "query" : { 
        "match_all" : {}
    }
}

I tested this query in Kibana and Elastic 5.5.2
