• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach tu)) xang xa hoi. hieu ve cau luc ngan hang vit ((ca tren) OR (la tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (sach tu)) xang xa hoi. hieu ve cau luc ngan hang vit ((ca tren) OR (la tren))".
