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