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