• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) or (nuoc sach)) ty xang ma hoa. hieu ((vu cham) OR (va cham)) duc va hanh lai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (nuoc sach)) ty xang ma hoa. hieu ((vu cham) OR (va cham)) duc va hanh lai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (nuoc sach)) ty xang ma hoa. hieu ((vu cham) OR (va cham)) duc va hanh lai cua triet".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (nuoc sach)) ty xang ma hoa. hieu ((vu cham) OR (va cham)) duc va hanh lai cua triet*.
