 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.
