• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty tang van hoa. sieu viet ((cac tac) OR (cac toc)) ((va hang) OR (va nang)) ca chua trieu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty tang van hoa. sieu viet ((cac tac) OR (cac toc)) ((va hang) or (va nang)) ca chua trieu~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty tang van hoa. sieu viet ((cac tac) OR (cac toc)) ((va hang) or (va nang)) ca chua trieu*.
