• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chinh sach)) - canh ((manh quang) OR (manh quan)) dung phuong dan phan tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chinh sach)) - canh ((manh quang) OR (manh quan)) dung phuong dan phan tu".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chinh sach)) - canh ((manh quang) OR (manh quan)) dung phuong dan phan tu*.
