• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu sach)) - thanh tuong dan nhung tuong dan ((than cau) OR (than cap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (chieu sach)) - thanh tuong dan nhung tuong dan ((than cau) or (than cap))".
