• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky lang van hoe. hieu van ((nam duc) OR (nam duoc)) va danh ((va cua) OR (va chua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky lang van hoe. hieu van ((nam duc) or (nam duoc)) va danh ((va cua) OR (va chua)) tre~".
• Adding a wildcard symbol may retrieve word variants: te sac ky lang van hoe. hieu van ((nam duc) or (nam duoc)) va danh ((va cua) OR (va chua)) tre*.
