# where the authorization header is passed from Kustvakt

# The connection is via WebSockets and each remote node
# returns the first x matches in a bunch only in form of sorting criteria
# for fast paging through results.
#
# After the results are returned, the results somehow should be validated
# to defend rogue nodes.

# The mechanism requires that the collation of the sorting is forwarded
# as well. This will override rank sorting on terms and fields
# (and is probably slow).
