So while browsing around today for this and that, I left my item search active while I traveled to another ward. To my surprise, my searched item (Lightning Shards) showed up in other wards! I experimented around with it a bit and found out that it works as such:
* The initial item search will only list how many of a given item are for sale. This works in either singles or stacks.
ex. a search result of 5 Undyed Canvas means that there are 5 listings, not 5 individual pieces or stacks per se. These listings can either be 5 seperate stacks of xx or just 5 retainers each selling 1 piece of canvas.
* This search result will only pertain to it's given ward.
ex. searching for a Silver Scpeter will only list how many are listed in the Spellcraft Ward.
* Even though the search system will only list an item in it's given ward, retainers in other wards will still show up with a star over their head if they have your searched item.
I didn't really see this posted elsewhere, so I thought I'd let you folks know!
