• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((((sach ty) OR (sach y))) OR (sach thu)) nang dai hoi. hieu ve cac dua ban hanh san cuc tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((((sach ty) OR (sach y))) or (sach thu)) nang dai hoi. hieu ve cac dua ban hanh san cuc tre".
• Adding a wildcard symbol may retrieve word variants: toc ((((sach ty) OR (sach y))) or (sach thu)) nang dai hoi. hieu ve cac dua ban hanh san cuc tre*.
