bug in the advanced shop search function

I don't know if this bug has been reported so far.
I used the advanced shop search function for my archer at level 40.
here is the list of ALL the items that should be available for my character, given by the store clerk:
Dual Kevlar
Chocobo Robe
Spikes
Book Of Peace
Regal Crown
Riot Shield

however, i found a bow at this level 40 named "Sacred Arrow" that i can use with my archer, and it is not in the list from the store clerk.
There must be a problem with the search function or with the item description...

edit : i know why this happened. The sacred arrow requires 1 MP to use it, but Archer has NO MP at all ! So i can buy this item, i can equip it as a weapon, but i cannot use it during the battle .
The advanced shop search function is finally more clever than the equip function.
I will make a new thread in the blacksmith forum to have this MP cost being removed ....
