elasticsearch - 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 '{
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}'

But i have NO term and simply want to delete all documents from that type, no matter what term. What is best practice to achieve this? Empty term does not work.

I believe if you combine the delete by query with a match all it should do what you are looking for, something like this (using your example):

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

Or you could just delete the type:

curl -XDELETE http://localhost:9200/twitter/tweet
