• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) tu hanh xa hoi. ((hieu ve) OR (hieu va)) cam xuc va thanh tai cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (thu sach)) tu hanh xa hoi. ((hieu ve) or (hieu va)) cam xuc va thanh tai cau treo*".
