[gnome-software/wip/rancell/ubuntu-3-20-1: 5/72] Limit search entry to 100 characters.



commit 4df93e7f3a038847c6463d4ef1687a5e5b500362
Author: Robert Ancell <robert ancell canonical com>
Date:   Fri May 12 11:39:26 2017 +1200

    Limit search entry to 100 characters.
    
    The search entry can be linked to a remote server - by limiting the number of
    characters this stops accidental input (e.g. cat sitting on keyboard) from
    generating continuous searches.
