• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang xa hoi. hieu ve ((cam tuc) or (nam thu)) va dan va ((chua vat) OR (thuat vat))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. hieu ve ((cam tuc) OR (nam thu)) va dan va ((chua vat) OR (thuat vat)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. hieu ve ((cam tuc) or (nam thu)) va dan va ((chua vat) OR (thuat vat))".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. hieu ve ((cam tuc) or (nam thu)) va dan va ((chua vat) OR (thuat vat))*.
