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 ky ((nang x) or (dang xay)) hoi. hieu va cham xuc va hanh lai ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky ((nang x) OR (dang xay)) hoi. hieu va cham xuc va hanh lai ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky ((nang x) or (dang xay)) hoi. hieu va cham xuc va hanh lai ((cua tre) OR (cua te))*".
