• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) 7 lang ha hoi. hieu ((ve cam) OR (ve cac)) tuc va thanh vi luu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) 7 lang ha hoi. hieu ((ve cam) or (ve cac)) tuc va thanh vi luu tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) 7 lang ha hoi. hieu ((ve cam) or (ve cac)) tuc va thanh vi luu tre*.
