• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (su sach)) phu lang xa hoi. hieu van cam xuc van hanh dao ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) phu lang xa hoi. hieu van cam xuc van hanh dao ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) phu lang xa hoi. hieu van cam xuc van hanh dao ((cua tre) or (cua triet))".
