• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ty nang xa hoi. ((lieu va) OR (thien van)) lam trang va tinh vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ty nang xa hoi. ((lieu va) or (thien van)) lam trang va tinh vi cua tre*".
