• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) lo vang xa hoi. ((lieu van) OR (lieu va)) cau luc va danh dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) lo vang xa hoi. ((lieu van) or (lieu va)) cau luc va danh dai cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) lo vang xa hoi. ((lieu van) or (lieu va)) cau luc va danh dai cua tre*.
