• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ly lang xa hoi. hieu va cham o ((va hanh) OR (va danh)) ((do cua) or (dai cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ly lang xa hoi. hieu va cham o ((va hanh) OR (va danh)) ((do cua) OR (dai cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ly lang xa hoi. hieu va cham o ((va hanh) OR (va danh)) ((do cua) or (dai cua)) te*".
