• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky dang ma hoi. lieu va cam ((luc va) OR (loc va)) danh vai ((cau treo) OR (cau triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky dang ma hoi. lieu va cam ((luc va) or (loc va)) danh vai ((cau treo) OR (cau triet))".
• Adding a wildcard symbol may retrieve word variants: tu cac ky dang ma hoi. lieu va cam ((luc va) or (loc va)) danh vai ((cau treo) OR (cau triet))*.
