• Performing a fuzzy search may retrieve terms with similar spellings: ((su tai) OR (su thi)) ky dang xa hoi. hieu ve cam duc van hinh ((thai cua) or (than cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su tai) OR (su thi)) ky dang xa hoi. hieu ve cam duc van hinh ((thai cua) OR (than cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su tai) OR (su thi)) ky dang xa hoi. hieu ve cam duc van hinh ((thai cua) or (than cua)) tre".
• Adding a wildcard symbol may retrieve word variants: ((su tai) OR (su thi)) ky dang xa hoi. hieu ve cam duc van hinh ((thai cua) or (than cua)) tre*.
