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