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