• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sach ly) OR (sach lo)) quang xa hoi. hieu ve ((cam duc) or (dao duc)) van thanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach ly) OR (sach lo)) quang xa hoi. hieu ve ((cam duc) OR (dao duc)) van thanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach ly) OR (sach lo)) quang xa hoi. hieu ve ((cam duc) or (dao duc)) van thanh vai cua te*".
