• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty ((nang xa) or (nang x)) hoi. hieu van chat xuc ((va hanh) OR (va danh)) tai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((nang xa) OR (nang x)) hoi. hieu van chat xuc ((va hanh) OR (va danh)) tai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((nang xa) or (nang x)) hoi. hieu van chat xuc ((va hanh) OR (va danh)) tai cau treo".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((nang xa) or (nang x)) hoi. hieu van chat xuc ((va hanh) OR (va danh)) tai cau treo*.
