You can currently search by zone under the advanced filter which is an awsome function. The only issues that exists is if you are sorting by multi pick orders and the order contains an item in the target zones but also items outside of the target zone it is returned in the search. A way to either elect to only display results that exist completly in the target zones or a way to exclude orders that contain items in certain zones would help. i.e we are looking for orders that contain 2-9 picks where the items are all contained in picking bins. So an order that contains 4 items in the picking bins and 2 items in pallet locations is not one of the orders we are targeting but it is being diplayed in the search results.
