This is in the patch notes but I can't figure out where this is in the game interface. Anyone know how to use this feature they added?

-------------------------
The following changes have been made to gear sets:
The appearance of glamoured items will now be saved.
The subcommand Search for Matching Items has been added to the Gear Set Viewer interface.
In the event an item is not in your armoury chest, this command will search your personal inventory, armoire, and retainer inventories.
