• Performing a fuzzy search may retrieve terms with similar spellings: tu ((san ky) OR (van ky)) lang van hoa. lieu va cao vuc van hanh ((di cua) or (dai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (van ky)) lang van hoa. lieu va cao vuc van hanh ((di cua) OR (dai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) OR (van ky)) lang van hoa. lieu va cao vuc van hanh ((di cua) or (dai cua)) triet".
• Adding a wildcard symbol may retrieve word variants: tu ((san ky) OR (van ky)) lang van hoa. lieu va cao vuc van hanh ((di cua) or (dai cua)) triet*.
