The @samp{search.file}, @samp{search.fs_label}, and @samp{search.fs_uuid}
commands are aliases for @samp{search --file}, @samp{search --label}, and
@samp{search --fs-uuid} respectively.
Also hints as to which device may be the most likely to contain the item
searched for may be given via the (@option{-h}, @option{--hint}) option with
a device name as an argument. If the argument ends with a comma, then partitions
on the device are also searched. Furthermore, platform specific hints may be
given via the options @option{--hint-ieee1275}, @option{--hint-bios},
@option{--hint-baremetal}, @option{--hint-efi}, and @option{--hint-arc}. When
specified, these options take an argument and operate like @option{--hint}, but
only on the specified platform.
