• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) OR (sach y)) dang ((xay hoi) or (tay hoi)). lieu va cao tuc va thanh ket va trien~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach y)) dang ((xay hoi) OR (tay hoi)). lieu va cao tuc va thanh ket va trien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sach y)) dang ((xay hoi) or (tay hoi)). lieu va cao tuc va thanh ket va trien".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sach y)) dang ((xay hoi) or (tay hoi)). lieu va cao tuc va thanh ket va trien*.
