When using Results Authorization, individual results will be checked to ensure
the search user has access to them. This can be wasteful if you know your
entire results use the same permissions, e.g. if a user can access
one thing, they can access everything.
You can set Authorization Target to Login Verification URL Only, and
if the Login Verification URL check is successful, the Search Appliance will
assume all the individual results are allowed and skip authorizing them
individually.
