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