As well as XDG_HOME_DIR for user defined launchers. See GNOME Admin
Guide for an overview on XDG desktop entry spec, menu definition spec
and basedir spec.
The algorithm should be something like
if $XDG_DATA_HOME == NULL then
find .desktop files in ~/.local/share
else find .desktop files in $XDG_DATA_HOME/applications/
if $XDG_DATA_DIRS == NULL then
find .desktop files in ~/.local/share
else find .desktop files in $XDG_DATA_DIRS/applications/
Please also note that fd.o desktop entry spec defines an Hidden key as
well as NoDisplay key. IMHO tracker should ignore them, as it ignores
files in trash.
