• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu lang xa hoi. hieu ve cac duc gia hanh ve ((((cau treo) OR (cau trieu))) or (cau triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu lang xa hoi. hieu ve cac duc gia hanh ve ((((cau treo) OR (cau trieu))) OR (cau triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu lang xa hoi. hieu ve cac duc gia hanh ve ((((cau treo) OR (cau trieu))) or (cau triet))".
• Adding a wildcard symbol may retrieve word variants: tu sach thu lang xa hoi. hieu ve cac duc gia hanh ve ((((cau treo) OR (cau trieu))) or (cau triet))*.
