• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((((lang xa) OR (lang ha))) or (lang van)) hoi. hieu van luat duoc va luan van cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((((lang xa) OR (lang ha))) OR (lang van)) hoi. hieu van luat duoc va luan van cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((((lang xa) OR (lang ha))) or (lang van)) hoi. hieu van luat duoc va luan van cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((((lang xa) OR (lang ha))) or (lang van)) hoi. hieu van luat duoc va luan van cua tre*.
