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