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 y nang x hoi. ((hieu viec) or (nhieu viec)) cac xuc ((va hanh) OR (va thanh)) dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang x hoi. ((hieu viec) OR (nhieu viec)) cac xuc ((va hanh) OR (va thanh)) dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x hoi. ((hieu viec) or (nhieu viec)) cac xuc ((va hanh) OR (va thanh)) dai cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang x hoi. ((hieu viec) or (nhieu viec)) cac xuc ((va hanh) OR (va thanh)) dai cua te*.
