• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((nang xa) OR (nang ma)) hoi. hieu van chat ((soc va) OR (hoc va)) danh dai cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((nang xa) or (nang ma)) hoi. hieu van chat ((soc va) OR (hoc va)) danh dai cua viet".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((nang xa) or (nang ma)) hoi. hieu van chat ((soc va) OR (hoc va)) danh dai cua viet*.
