• Performing a fuzzy search may retrieve terms with similar spellings: so dang ky sang ((tao hoi) OR (tao khoi)). lieu va cac phuc cam ((dan di) or (dan dat)) cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so dang ky sang ((tao hoi) OR (tao khoi)). lieu va cac phuc cam ((dan di) OR (dan dat)) cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so dang ky sang ((tao hoi) OR (tao khoi)). lieu va cac phuc cam ((dan di) or (dan dat)) cua tu".
• Adding a wildcard symbol may retrieve word variants: so dang ky sang ((tao hoi) OR (tao khoi)). lieu va cac phuc cam ((dan di) or (dan dat)) cua tu*.
