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