== Bulk API
The bulk API makes it possible to perform many index/delete operations
in a single API call. This can greatly increase the indexing speed. The
REST API endpoint is `/_bulk`, and it expects the following JSON
in a single API call. This can greatly increase the indexing speed.
.Client support for bulk requests

Some of the officially supported clients provide helpers to assist with
bulk requests and reindexing of documents from one index to another:

processing large amounts of data, e.g. in order to reindex the contents of one
index into a new index with a different configuration.
.Client support for scrolling and reindexing
*********************************************
Some of the officially supported clients provide helpers to assist with
scrolled searches and reindexing of documents from one index to another:
Perl::
See https://metacpan.org/pod/Search::Elasticsearch::Bulk[Search::Elasticsearch::Bulk]

NOTE: The results that are returned from a scroll request reflect the state of
the index at the time that the initial `search` request was made, like a
snapshot in time. Subsequent changes to documents (index, update or delete)
