• Performing a fuzzy search may retrieve terms with similar spellings: vu khac tu ang xa hoi. hieu va cam ((luc van) OR (duc van)) hanh tri ((cua triet) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu khac tu ang xa hoi. hieu va cam ((luc van) OR (duc van)) hanh tri ((cua triet) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu khac tu ang xa hoi. hieu va cam ((luc van) OR (duc van)) hanh tri ((cua triet) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: vu khac tu ang xa hoi. hieu va cam ((luc van) OR (duc van)) hanh tri ((cua triet) or (cuu tre))*.
