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 have these alternatives:

1) Delete a whole index:

curl -XDELETE 'http://localhost:9200/indexName'             

example:

curl -XDELETE 'http://localhost:9200/mentorz'

For more details you can find here -https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-delete-index.html

2) Delete by Query to those that match:

curl -XDELETE 'http://localhost:9200/mentorz/users/_query' -d                
    '{
        "query":
            {
                "match_all": {}
            }
    }'

*Here mentorz is an index name and users is a type
