• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((tu lang) OR (tay lang)) xa hoi. thien van ((nam duc) OR (nam duoc)) van hang di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tu lang) or (tay lang)) xa hoi. thien van ((nam duc) OR (nam duoc)) van hang di cua te".
• Adding a wildcard symbol may retrieve word variants: te sach ((tu lang) or (tay lang)) xa hoi. thien van ((nam duc) OR (nam duoc)) van hang di cua te*.
