You can use urlpath_regex to block search queries in most search
engines.

acl search_keywords urlpath_regex -i \?.*(\+|=|%..)porn(o?)(\+|&|%|$)
\?.*(\+|=|%..)pussy(\+|&|%|$) [etc]

http_access deny search_keywords

Explanation of the regex pattern:

-i case insensitive

\? look for a ? in the URL
.* followed by any characters
(\+|=|%..) + (space) = or any %nn escape
porn(o?) porn or alternatively porno
(\+|&|%|$) followed by + (space) & (query separator)
                % (%nn escape) or nothing
