• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky dang xa hoi. hieu va ((chat xuc) OR (chat huu)) ((va thanh) OR (va hanh)) vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky dang xa hoi. hieu va ((chat xuc) OR (chat huu)) ((va thanh) or (va hanh)) vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky dang xa hoi. hieu va ((chat xuc) OR (chat huu)) ((va thanh) or (va hanh)) vi cua tre*.
