• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ((ty nang) OR (ty xang)) xa hoi. hieu ve cap cuu va thanh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) ((ty nang) OR (ty xang)) xa hoi. hieu ve cap cuu va thanh vai cua triet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (vu sach)) ((ty nang) OR (ty xang)) xa hoi. hieu ve cap cuu va thanh vai cua triet*.
