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