You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty ((lang xa) OR (lang van)) hoi. hieu ve nam thuc ban ((thanh le) or (thinh le)) cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((lang xa) OR (lang van)) hoi. hieu ve nam thuc ban ((thanh le) OR (thinh le)) cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((lang xa) OR (lang van)) hoi. hieu ve nam thuc ban ((thanh le) or (thinh le)) cua vat".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((lang xa) OR (lang van)) hoi. hieu ve nam thuc ban ((thanh le) or (thinh le)) cua vat*.
