• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty nang mai hoi. lieu va cham cuu ban thanh vi ((cua te) OR (((cu tren) OR (dat tren))))~.
• Adding a wildcard symbol may retrieve word variants: so sach ty nang mai hoi. lieu va cham cuu ban thanh vi ((cua te) or (((cu tren) or (dat tren))))*.
