• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh ((trang va) OR (trung ha)) ((nhung cong) OR (thong cong)) tan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh ((trang va) or (trung ha)) ((nhung cong) OR (thong cong)) tan toan cao".
