• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu sach)) ky dang ma hoa. thien dan ((ca dua) OR (cay dua)) ban thanh tai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) or (tu sach)) ky dang ma hoa. thien dan ((ca dua) OR (cay dua)) ban thanh tai cua tre*".
