• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (cac ky)) dang xay hoi. thien ((van lam) OR (van nam)) duc ban thanh doi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) OR (cac ky)) dang xay hoi. thien ((van lam) or (van nam)) duc ban thanh doi cua tre".
