• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach y lang ha hoi. thien van cam luc ((va hanh) OR (va thanh)) ((trinh cua) OR (tinh cua)) tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y lang ha hoi. thien van cam luc ((va hanh) OR (va thanh)) ((trinh cua) or (tinh cua)) tu".
