• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach ty)) dang xa hoi. hieu va dao duc va ((danh vai) OR (doanh va)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach ty)) dang xa hoi. hieu va dao duc va ((danh vai) or (doanh va)) cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach ty)) dang xa hoi. hieu va dao duc va ((danh vai) or (doanh va)) cua te*.
