• If you are trying to use Boolean operators, they must be ALL CAPS: vu sai kho dang ((van hoi) OR (van hoe)). hieu ((ve cam) OR (ve cac)) xuc va danh de cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sai kho dang ((van hoi) or (van hoe)). hieu ((ve cam) OR (ve cac)) xuc va danh de cua tre".
• Adding a wildcard symbol may retrieve word variants: vu sai kho dang ((van hoi) or (van hoe)). hieu ((ve cam) OR (ve cac)) xuc va danh de cua tre*.
