• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang xa hoi. hieu ((ve cam) OR (va cac)) ((lo va) OR (lao va)) doanh va cua te~.
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang xa hoi. hieu ((ve cam) or (va cac)) ((lo va) or (lao va)) doanh va cua te*.
