• If you are trying to use Boolean operators, they must be ALL CAPS: toc thieu sang - thanh tran luan hung ((((cong vang) OR (cong ngang))) OR (song van)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc thieu sang - thanh tran luan hung ((((cong vang) OR (cong ngang))) or (song van)) toan cau*".
