• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach ty nang xa hoi. hieu san pham thuc ((vat hanh) or (((va hanh) OR (va danh)))) te cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ty nang xa hoi. hieu san pham thuc ((vat hanh) OR (((va hanh) OR (va danh)))) te cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ty nang xa hoi. hieu san pham thuc ((vat hanh) or (((va hanh) OR (va danh)))) te cua te*".
