• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sanh) OR (thu sach)) ky lang xa hoi. ((thi van) OR (thi hanh)) cam tuc va thanh vai cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sanh) or (thu sach)) ky lang xa hoi. ((thi van) OR (thi hanh)) cam tuc va thanh vai cau tren".
• Adding a wildcard symbol may retrieve word variants: ((so sanh) or (thu sach)) ky lang xa hoi. ((thi van) OR (thi hanh)) cam tuc va thanh vai cau tren*.
