• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) ((nang duoc) OR (nganh duoc)) hoi. thien van lam tuc xa hanh vi va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) ((nang duoc) or (nganh duoc)) hoi. thien van lam tuc xa hanh vi va triet".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach y)) ((nang duoc) or (nganh duoc)) hoi. thien van lam tuc xa hanh vi va triet*.
