This setting is the maximum total time in seconds to spend searching
and authorizing results, during Results Authorization. The maximum
setting value is -1 for no limit, i.e. let Search Timeout
(here) cancel the search if reached. Any
other negative value is relative to Search Timeout. Thus the
default (if empty) of -5 means stop searching 5 seconds before
Search Timeout, so that there are a few seconds left to send the
results to the user.
