I find it easier to deal with and modify the search parameters directly in the
URL query string for consistent search results to scrape: just (re-)move the
'"'s or paste-select-cut between Summer and Standard, to ensure other parameter
settings are unchanged.

The URL "+" appears as " " in the search box and vice-versa " " in the search
box appears as "+" in the URL.
This is in the URL encoding spec for the query string parameter value default
application/x-www-form-urlencoded content type, also requiring literal value "+"
be URL-/%-encoded as "%2b".
That is what those query strings contain instead of "+" or " ", and they appear
to be disrupting the search.
