• If you are trying to use Boolean operators, they must be ALL CAPS: ve cac ky lang xa hoi. ((lieu va) OR (hieu qua)) cam duc ((ban nang) OR (ban dang)) vinh cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ve cac ky lang xa hoi. ((lieu va) or (hieu qua)) cam duc ((ban nang) OR (ban dang)) vinh cua tre".
• Adding a wildcard symbol may retrieve word variants: ve cac ky lang xa hoi. ((lieu va) or (hieu qua)) cam duc ((ban nang) OR (ban dang)) vinh cua tre*.
