• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach thi hanh xa hoi. thien van van hoc va danh ((dinh cuu) OR (((di cau) OR (da cau)))) tre.
• Adding a wildcard symbol may retrieve word variants: thu sach thi hanh xa hoi. thien van van hoc va danh ((dinh cuu) or (((di cau) or (da cau)))) tre*.
