• Performing a fuzzy search may retrieve terms with similar spellings: te san ky nang x hoi. ((hieu ve) or (hieu van)) cam tuc ((va dinh) OR (van dinh)) lam cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te san ky nang x hoi. ((hieu ve) OR (hieu van)) cam tuc ((va dinh) OR (van dinh)) lam cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te san ky nang x hoi. ((hieu ve) or (hieu van)) cam tuc ((va dinh) OR (van dinh)) lam cua te".
• Adding a wildcard symbol may retrieve word variants: te san ky nang x hoi. ((hieu ve) or (hieu van)) cam tuc ((va dinh) OR (van dinh)) lam cua te*.
