[Matthias Clasen <matthiasc src gnome org>]

commit 73d0bc7191bee7f7e11fe2697899aa70d5582d03
Author: Matthias Clasen <mclasen redhat com>

    Improve recipe search capabilities
    
    Make searching by author exact, and add a way to search
    by season. This will be used in future commits when we
    convert the list page to populate asynchronously.
