• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) thu lang xa hoi. hieu ((ve cam) OR (va cam)) tuc ban thanh le cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) thu lang xa hoi. hieu ((ve cam) or (va cam)) tuc ban thanh le cua vat".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) thu lang xa hoi. hieu ((ve cam) or (va cam)) tuc ban thanh le cua vat*.
