• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ((ky danh) OR (ky nang)) xay hoi. hieu va ((cam loc) OR (cam lo)) ban thanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ((ky danh) or (ky nang)) xay hoi. hieu va ((cam loc) OR (cam lo)) ban thanh vai cua te".
