• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky ((lang xa) OR (lang van)) hoi. hieu ((van cau) or (van nam)) xuc gia thanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky ((lang xa) OR (lang van)) hoi. hieu ((van cau) OR (van nam)) xuc gia thanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky ((lang xa) OR (lang van)) hoi. hieu ((van cau) or (van nam)) xuc gia thanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: vu sach ky ((lang xa) OR (lang van)) hoi. hieu ((van cau) or (van nam)) xuc gia thanh vi cua triet*.
