• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly hang xa hoi. ((((hieu van) OR (hieu ve))) OR (lieu va)) bac luc gia thanh ban cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly hang xa hoi. ((((hieu van) OR (hieu ve))) or (lieu va)) bac luc gia thanh ban cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach ly hang xa hoi. ((((hieu van) OR (hieu ve))) or (lieu va)) bac luc gia thanh ban cua tre*.
