• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y nang ma hoi. hieu van lam xuc ((xa hanh) OR (xa thanh)) ((vi cua) or (di cua)) tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang ma hoi. hieu van lam xuc ((xa hanh) OR (xa thanh)) ((vi cua) OR (di cua)) tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang ma hoi. hieu van lam xuc ((xa hanh) OR (xa thanh)) ((vi cua) or (di cua)) tu".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang ma hoi. hieu van lam xuc ((xa hanh) OR (xa thanh)) ((vi cua) or (di cua)) tu*.
