• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang x hoi. hieu van chat xuc cam ((dan vai) OR (dan tai)) ((cua tre) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang x hoi. hieu van chat xuc cam ((dan vai) OR (dan tai)) ((cua tre) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang x hoi. hieu van chat xuc cam ((dan vai) OR (dan tai)) ((cua tre) or (cua tu))*.
