• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach lo)) ((hang xa) OR (hang va)) hoi. hieu va chat truc va hanh dai cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (sach lo)) ((hang xa) OR (hang va)) hoi. hieu va chat truc va hanh dai cua tu~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) or (sach lo)) ((hang xa) OR (hang va)) hoi. hieu va chat truc va hanh dai cua tu*.
