"GNOME Do provides instantaneous, action-oriented
desktop search results that adapt to reflect your habits and
preferences. Unlike other search tools that present search results
as flat, homogeneous lists, "GNOME Do" provides familiar graphical
depictions of search results that assure you that your intent is
being realized correctly; searching for "mom" will show a picture
of mom (if you had your moms picturer and indeed the filename had
mom in it)."
