• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh ky nang cao hoi. hieu ve cham o ((ban hanh) OR (va dan)) ((di cuu) OR (di cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh ky nang cao hoi. hieu ve cham o ((ban hanh) or (va dan)) ((di cuu) OR (di cua)) tre".
• Adding a wildcard symbol may retrieve word variants: thuat lanh ky nang cao hoi. hieu ve cham o ((ban hanh) or (va dan)) ((di cuu) OR (di cua)) tre*.
