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