• Performing a fuzzy search may retrieve terms with similar spellings: su sach tu dang cac phoi. hieu ve ((((cac duc) OR (cac dac))) or (cao duc)) ban lanh hai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tu dang cac phoi. hieu ve ((((cac duc) OR (cac dac))) OR (cao duc)) ban lanh hai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach tu dang cac phoi. hieu ve ((((cac duc) OR (cac dac))) or (cao duc)) ban lanh hai cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach tu dang cac phoi. hieu ve ((((cac duc) OR (cac dac))) or (cao duc)) ban lanh hai cua triet*.
