• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach thu)) vang xa hoi. ((hieu viec) OR (hieu ve)) cua xuc va hanh di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (sach thu)) vang xa hoi. ((hieu viec) OR (hieu ve)) cua xuc va hanh di cua te*".
