• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y dang van hoi. lieu va ((cac nuoc) OR (dat nuoc)) va ((thanh vi) OR (thanh va)) cau theo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y dang van hoi. lieu va ((cac nuoc) OR (dat nuoc)) va ((thanh vi) or (thanh va)) cau theo".
