You are always returning a true value.  A SearchOp's coderef needs
to return true if a match is found or false if no match is found.

Try something like this instead:

    CodeDef not_tags SearchOp
    CodeDef not_tags Routine <<EOR
    sub {
        my ($self, $i, $pat) = @_;
        $pat = qr/$pat/i;

        return sub {
            my $string = shift;

            $string =~ s:<[/\w].+?>::gi;
            return $string =~ $pat;
        };
    }
    EOR
