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

• Performing a fuzzy search may retrieve terms with similar spellings: so sach y ((nang xa) or (nang x)) hoi. hieu ve cham xuc va han thai ((va thieu) OR (va thiet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach y ((nang xa) OR (nang x)) hoi. hieu ve cham xuc va han thai ((va thieu) OR (va thiet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y ((nang xa) or (nang x)) hoi. hieu ve cham xuc va han thai ((va thieu) OR (va thiet))".
• Adding a wildcard symbol may retrieve word variants: so sach y ((nang xa) or (nang x)) hoi. hieu ve cham xuc va han thai ((va thieu) OR (va thiet))*.
