• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) or (su cac)) ky nang xa hoi. hieu ve ((giap nguoi) OR (gap nguoi)) san hanh kem cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su cac)) ky nang xa hoi. hieu ve ((giap nguoi) OR (gap nguoi)) san hanh kem cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su cac)) ky nang xa hoi. hieu ve ((giap nguoi) OR (gap nguoi)) san hanh kem cua tu".
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su cac)) ky nang xa hoi. hieu ve ((giap nguoi) OR (gap nguoi)) san hanh kem cua tu*.
