• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang co loi. thien van nam ((duc van) OR (duc tan)) ((thanh vi) OR (thanh ve)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang co loi. thien van nam ((duc van) OR (duc tan)) ((thanh vi) or (thanh ve)) cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang co loi. thien van nam ((duc van) OR (duc tan)) ((thanh vi) or (thanh ve)) cua triet*.
