Can't use the prefix ">" before an item to switch disk search mode

I’m a win7 & win8 user, and i encounter a problem when i use listary, when i want to search an item from the entire disk, i call up the listary, type “>” and follow with an item which i want, but no records coming up, could this be a bug?

Listary now searches the entire disk by default. The “>” is not needed. Simply type your search query directly.
