• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((nang ma) OR (mang may)) hoi. hiem he nam thu xa ((danh dai) OR (danh di)) cua tre.
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((nang ma) or (mang may)) hoi. hiem he nam thu xa ((danh dai) or (danh di)) cua tre*.
