• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang xa hoi. ((thien van) OR (hieu va)) cau chuc va thanh ((vai cua) OR (lai cua)) viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang xa hoi. ((thien van) or (hieu va)) cau chuc va thanh ((vai cua) OR (lai cua)) viet*".
