• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) OR (su xac)) ky nang xa hoi. hieu va cam thuc hanh hanh ((vi cua) or (di cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky nang xa hoi. hieu va cam thuc hanh hanh ((vi cua) OR (di cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su xac)) ky nang xa hoi. hieu va cam thuc hanh hanh ((vi cua) or (di cua)) tre*".
