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

• Performing a fuzzy search may retrieve terms with similar spellings: va ban ky ((nang xa) or (lang xa)) hoi. hieu viec cac luc va thanh vai ((cua te) OR (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: va ban ky ((nang xa) OR (lang xa)) hoi. hieu viec cac luc va thanh vai ((cua te) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "va ban ky ((nang xa) or (lang xa)) hoi. hieu viec cac luc va thanh vai ((cua te) OR (cua tu))*".
