• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sai) OR (thu tai)) ky nang xa hoi. thien van bao duc van hanh vai ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sai) OR (thu tai)) ky nang xa hoi. thien van bao duc van hanh vai ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sai) OR (thu tai)) ky nang xa hoi. thien van bao duc van hanh vai ((cua te) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: ((thu sai) OR (thu tai)) ky nang xa hoi. thien van bao duc van hanh vai ((cua te) or (cua tu))*.
