• Performing a fuzzy search may retrieve terms with similar spellings: vu ((bach ty) or (sach tu)) hang xa hoi. hieu van cam duc van ((thanh de) OR (thanh do)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((bach ty) OR (sach tu)) hang xa hoi. hieu van cam duc van ((thanh de) OR (thanh do)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((bach ty) or (sach tu)) hang xa hoi. hieu van cam duc van ((thanh de) OR (thanh do)) cua te".
• Adding a wildcard symbol may retrieve word variants: vu ((bach ty) or (sach tu)) hang xa hoi. hieu van cam duc van ((thanh de) OR (thanh do)) cua te*.
