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.
