• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((bach ty) OR (bach thu)) hang xa hoi. hieu van cam duc ((ban nhan) OR (ban than)) vien cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((bach ty) or (bach thu)) hang xa hoi. hieu van cam duc ((ban nhan) OR (ban than)) vien cua te".
• Adding a wildcard symbol may retrieve word variants: vu ((bach ty) or (bach thu)) hang xa hoi. hieu van cam duc ((ban nhan) OR (ban than)) vien cua te*.
