• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu hang van hoi. hieu ve cac ((tuc cam) OR (tuc cham)) nang dai ((va triet) or (va thiet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu hang van hoi. hieu ve cac ((tuc cam) OR (tuc cham)) nang dai ((va triet) OR (va thiet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu hang van hoi. hieu ve cac ((tuc cam) OR (tuc cham)) nang dai ((va triet) or (va thiet))".
• Adding a wildcard symbol may retrieve word variants: tu sach thu hang van hoi. hieu ve cac ((tuc cam) OR (tuc cham)) nang dai ((va triet) or (va thiet))*.
