Deleting first n documents from index

Elastic Stack Elasticsearch
1

Hey, this is a pretty simple question but after much searching I'm still
stumped. Basically I want to create a delete by query that deletes the
first n documents from a given index. The only thing I found relating to
restricting the size were the from/size parameters
http://www.elasticsearch.org/guide/reference/api/search/from-size/ but as
far as I'm aware that isn't compatible with the query DSL. I also found the
limit query but that only limits the documents to retrieve per shard. I'm
probably missing something really obvious but I'm completely stumped.

Any help would be greatly appreciated, Thanks

Hey,

a delete by query will delete all documents that match the query not just
the top N results. How do you define the first N? are they the oldest docs
in the index? maybe you can give some details so we can help better.
