Although the information of a package maintainer can be retrieved from a package page, that information cannot be retrieved from the searching package page.
For instance, the maintainer info is accessible from here (by clicking his/her name): http://aur.archlinux.org/packages.php?ID=7111
whereas clicking on his/her name from here doesn't work: http://aur.archlinux.org/packages.php?K=uwolfer&SeB=m
Clicking on the name in the searching package page actually filters the search result with that maintainer. But I'm wondering if it would not be more consistent to display the maintainer information instead.
