• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ((nang xa) or (((lang xa) OR (lang ha)))) hoi. hieu van hac xuc va danh tai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((nang xa) OR (((lang xa) OR (lang ha)))) hoi. hieu van hac xuc va danh tai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang xa) or (((lang xa) OR (lang ha)))) hoi. hieu van hac xuc va danh tai cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((nang xa) or (((lang xa) OR (lang ha)))) hoi. hieu van hac xuc va danh tai cua triet*.
