• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky nang xa hoi. hieu cao cua trung va danh dai ((((cua tre) OR (cua te))) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky nang xa hoi. hieu cao cua trung va danh dai ((((cua tre) OR (cua te))) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky nang xa hoi. hieu cao cua trung va danh dai ((((cua tre) OR (cua te))) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: thu sach ky nang xa hoi. hieu cao cua trung va danh dai ((((cua tre) OR (cua te))) or (cuu tre))*.
