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

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