• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sai ky) OR (sac ky)) trang ha hoi. ((hieu van) OR (lieu va)) lam duc ban thanh de cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sai ky) OR (sac ky)) trang ha hoi. ((hieu van) or (lieu va)) lam duc ban thanh de cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sai ky) OR (sac ky)) trang ha hoi. ((hieu van) or (lieu va)) lam duc ban thanh de cua tre*.
