• If you are trying to use Boolean operators, they must be ALL CAPS: vu bach ((ty nang) OR (ky nang)) ma hoi. hieu ve nham thuc va danh ((thu cua) OR (tu cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu bach ((ty nang) or (ky nang)) ma hoi. hieu ve nham thuc va danh ((thu cua) OR (tu cua)) te*".
