The search specification can be found in [data session last_search].

The following should give you a space-separated list of search fields:

    [calc]
        my @fields;
        foreach (split('/',$Session->{last_search})){
            /^(.+?)\s*=\s*(.+)$/;
            next unless $1 eq 'sf';
            push(@fields,$2);
        }
        join(' ',@fields);
    [/calc]

You can adapt that to extract any information you need; The following
should just dump the whole search parameter list:

    [calc]
        my $buf = '';
        foreach (split('/',$Session->{last_search})){
            /^(.+?)\s*=\s*(.+)$/;
            my ($name,$val) = ($1,$2);
            $val =~ s/%(.{2})/chr(hex($1))/ge;
            $buf .= qq{$name = "$val"<br>};
        }
        $buf;
    [/calc]

Remember that the "search file" will default to "products", or whatever
you have in your ProductFiles directive (catalog.cfg), if not specified
in the search parameters.
