• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (thuat song)) ky tang xa hoi. hieu tu cham xuc van hanh di ((cua te) OR (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thuat song)) ky tang xa hoi. hieu tu cham xuc van hanh di ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thuat song)) ky tang xa hoi. hieu tu cham xuc van hanh di ((cua te) OR (cua tu))".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thuat song)) ky tang xa hoi. hieu tu cham xuc van hanh di ((cua te) OR (cua tu))*.
