• Performing a fuzzy search may retrieve terms with similar spellings: doc ((hieu manh) or (hieu nganh)) - thanh truong hua khong cong san ((chan tu) OR (chon tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu manh) OR (hieu nganh)) - thanh truong hua khong cong san ((chan tu) OR (chon tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu manh) or (hieu nganh)) - thanh truong hua khong cong san ((chan tu) OR (chon tu))".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu manh) or (hieu nganh)) - thanh truong hua khong cong san ((chan tu) OR (chon tu))*.
