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