• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((o lang) OR (hoa lang)) xa hoi. hieu ve cac tu van anh vi ((cua tuc) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((o lang) or (hoa lang)) xa hoi. hieu ve cac tu van anh vi ((cua tuc) OR (cua tu))".
• Adding a wildcard symbol may retrieve word variants: te sach ((o lang) or (hoa lang)) xa hoi. hieu ve cac tu van anh vi ((cua tuc) OR (cua tu))*.
