• Performing a fuzzy search may retrieve terms with similar spellings: toc sach thu mang xa hoi. hieu van lam xuc ((va hanh) or (((van hanh) OR (ban hanh)))) vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach thu mang xa hoi. hieu van lam xuc ((va hanh) OR (((van hanh) OR (ban hanh)))) vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach thu mang xa hoi. hieu van lam xuc ((va hanh) or (((van hanh) OR (ban hanh)))) vai cua te*".
