chrome* doesn't recognize search

[xenoterracide]

in many searches... you can search the site once, and then the next time you want to search the site, in chrome's url bar you can put the domain, hit tab and you can search the site. this works well with search.cpan.org however doesn't seem to work with search.metacpan.org

I don't actually understand how chrome detects this, so I can't speak on what's missing
