• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tai san xa hoi. hieu ((va bai) OR (va cam)) ((xuc va) OR (luc va)) manh dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tai san xa hoi. hieu ((va bai) or (va cam)) ((xuc va) OR (luc va)) manh dai cua tre".
