• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((trang xa) OR (trang ha)) hoi. hieu van nam xua va dinh ((van chat) OR (van dao)) treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((trang xa) OR (trang ha)) hoi. hieu van nam xua va dinh ((van chat) or (van dao)) treo".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((trang xa) OR (trang ha)) hoi. hieu van nam xua va dinh ((van chat) or (van dao)) treo*.
