shell can do it, so it should not be too difficult to lift that part out of the code and incorporate it into a cpansearch
Actually, it can be as easy as:
my $search = shift @ARGV;
my @modules = CPAN::Shell->expand("Module","/$search/");
say CPAN::Module::as_glimpse($_) for @modules;
Add some option handling and argument checking and you are done!
A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
