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