• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty hang ca hoi. hieu van cam ((xuc va) OR (tuc va)) ((thanh vien) OR (thanh van)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty hang ca hoi. hieu van cam ((xuc va) OR (tuc va)) ((thanh vien) or (thanh van)) cua tre".
