• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ly ((nang xa) OR (nang ma)) hoi. hieu ve cham soc va thanh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (su sach)) ly ((nang xa) OR (nang ma)) hoi. hieu ve cham soc va thanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (su sach)) ly ((nang xa) OR (nang ma)) hoi. hieu ve cham soc va thanh vi cua triet*.
