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