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