• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) OR (sach y)) xang ((ma hoi) or (ma hoa)). hieu qua cao su va thanh lap cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) xang ((ma hoi) OR (ma hoa)). hieu qua cao su va thanh lap cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach y)) xang ((ma hoi) or (ma hoa)). hieu qua cao su va thanh lap cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) OR (sach y)) xang ((ma hoi) or (ma hoa)). hieu qua cao su va thanh lap cuu tre*.
