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