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