• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty nang mai hoi. lieu va ((chat xuc) or (cam xuc)) va doanh ban ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang mai hoi. lieu va ((chat xuc) OR (cam xuc)) va doanh ban ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang mai hoi. lieu va ((chat xuc) or (cam xuc)) va doanh ban ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang mai hoi. lieu va ((chat xuc) or (cam xuc)) va doanh ban ((cua triet) OR (su triet))*.
