• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach tri vu khanh hoa phau thong ) OR ( te sach tri tu hanh hoa hang (thuong OR phuong) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach tri vu khanh hoa phau thong ) or ( te sach tri tu hanh hoa hang (thuong OR phuong) ))~".
• Adding a wildcard symbol may retrieve word variants: (( te sach tri vu khanh hoa phau thong ) or ( te sach tri tu hanh hoa hang (thuong OR phuong) ))*.
