• Performing a fuzzy search may retrieve terms with similar spellings: te sach y sang ((tao hoi) OR (tao khoi)). lieu va chat quoc giao thanh lap ((cuu tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y sang ((tao hoi) OR (tao khoi)). lieu va chat quoc giao thanh lap ((cuu tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y sang ((tao hoi) OR (tao khoi)). lieu va chat quoc giao thanh lap ((cuu tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: te sach y sang ((tao hoi) OR (tao khoi)). lieu va chat quoc giao thanh lap ((cuu tre) or (cua te))*.
