• If you are trying to use Boolean operators, they must be ALL CAPS: (( ve cach hoc thuoc sach dang he trong ) OR ( te anh thuc thuc hai phong do trung ))~.
• Adding a wildcard symbol may retrieve word variants: (( ve cach hoc thuoc sach dang he trong ) or ( te anh thuc thuc hai phong do trung ))*.
