• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach y)) hang x hoi. ((hieu ve) OR (hieu va)) cam tu va thanh van cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) OR (sach y)) hang x hoi. ((hieu ve) or (hieu va)) cam tu va thanh van cua te".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ty) OR (sach y)) hang x hoi. ((hieu ve) or (hieu va)) cam tu va thanh van cua te*.
