This is a minor annoyance, but an annoyance nonetheless: when one uses the item mapper tool, one generally has a very specific idea of what item needs to be mapped to another collection. Typically a repository manager has carefully prepared a list of item handles. The searching on an item handle in the item mapper for a specific collection invariably produces many irrelevant results. One has to "be careful" to pick the correct item, when, presumably, there should be only one match for an item's handle, and one has already "been careful" in entering the handle. I think there should probably be a way to either allow a user to "truncate" the search, or otherwise allow for precision when searching for a single item.
