• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ((ky lang) OR (ky nang)) xa hoi. hieu van lam xuc va thanh ((vai cua) OR (hai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ((ky lang) OR (ky nang)) xa hoi. hieu van lam xuc va thanh ((vai cua) or (hai cua)) tre".
