• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach tri ((du anh) OR (duy anh)) khoa thu thong ) OR ( thu sach tri tue bach dan hoa cong ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach tri ((du anh) OR (duy anh)) khoa thu thong ) or ( thu sach tri tue bach dan hoa cong ))~".
• Adding a wildcard symbol may retrieve word variants: (( te sach tri ((du anh) OR (duy anh)) khoa thu thong ) or ( thu sach tri tue bach dan hoa cong ))*.
