• Performing a fuzzy search may retrieve terms with similar spellings: so dang ky ((nang xa) or (lang xa)) hoi. hieu va co suc gia ((thanh va) OR (thanh ha)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so dang ky ((nang xa) OR (lang xa)) hoi. hieu va co suc gia ((thanh va) OR (thanh ha)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so dang ky ((nang xa) or (lang xa)) hoi. hieu va co suc gia ((thanh va) OR (thanh ha)) cua te".
• Adding a wildcard symbol may retrieve word variants: so dang ky ((nang xa) or (lang xa)) hoi. hieu va co suc gia ((thanh va) OR (thanh ha)) cua te*.
