Specifying document type in search query - performance impact for single shard index

Elastic Stack Elasticsearch
1

Hi all,

If I have an elasticsearch index with a single shard and 0 replicas. Will
specifying a document-type part of the match_all query help in performance
(i.e narrowing down the result-set)?

i.e 'http://localhost:9200/my-index/my-doc-type/_search vs
'http://localhost:9200/my-index/_search

This is what I found from the documentation

"When we search for documents of a particular type, Elasticsearch simply
uses a filter on the _type field to restrict results to documents of that
type."

So it seems the answer is yes.
