• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang ro lai. hieu ve cac xuc van hanh ((thai cua) or (((than cua) OR (nhan cua)))) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ro lai. hieu ve cac xuc van hanh ((thai cua) OR (((than cua) OR (nhan cua)))) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ro lai. hieu ve cac xuc van hanh ((thai cua) or (((than cua) OR (nhan cua)))) tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ro lai. hieu ve cac xuc van hanh ((thai cua) or (((than cua) OR (nhan cua)))) tre*.
