• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - hanh ((hang nam) OR (hoang nam)) ((nhung cong) OR (thong cong)) thanh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - hanh ((hang nam) OR (hoang nam)) ((nhung cong) or (thong cong)) thanh toan cau*".
