• Performing a fuzzy search may retrieve terms with similar spellings: tu can ky va dap phoi. hieu ((va cac) or (vien cac)) xuc va danh ((vi cua) OR (vai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu can ky va dap phoi. hieu ((va cac) OR (vien cac)) xuc va danh ((vi cua) OR (vai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can ky va dap phoi. hieu ((va cac) or (vien cac)) xuc va danh ((vi cua) OR (vai cua)) tre".
