• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) or (te sach)) ky dang ha noi. hieu va cam xuc van ((thanh vi) OR (thanh ve)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (te sach)) ky dang ha noi. hieu va cam xuc van ((thanh vi) OR (thanh ve)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (te sach)) ky dang ha noi. hieu va cam xuc van ((thanh vi) OR (thanh ve)) cua triet".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (te sach)) ky dang ha noi. hieu va cam xuc van ((thanh vi) OR (thanh ve)) cua triet*.
