• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang van hoc. ((hieu va) OR (lieu va)) cam loc gia thanh tri ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang van hoc. ((hieu va) OR (lieu va)) cam loc gia thanh tri ((cua triet) or (cua viet))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang van hoc. ((hieu va) OR (lieu va)) cam loc gia thanh tri ((cua triet) or (cua viet))*.
