It does not search in Artifact Inventory - neither for artifacts nor lightstones.

It'd be helpful if "Find My Item" could search more areas.

Artifacts, Transport Wagons, Mounts, Patrigio's and other inventory bags, Tool Bag?

(Curiously, Crystals was already made to be searchable.)

Maybe even Challenges and Mail?

(This had me confused when searching storages for my Fughar's Timepiece; realizing much later that Transport Wagons are storage-adjacent but not included, which is where it was. Goodbye Timepiece! Goodbye Maegu rewards! Hello next season's timepiece character, I guess. >_<;;

Totally agree.

I agree it would be helpful if it searched everywhere.
