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 xa hoi. hieu van ((bao luc) OR (bao thuc)) tan thanh vai ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. hieu van ((bao luc) OR (bao thuc)) tan thanh vai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu van ((bao luc) OR (bao thuc)) tan thanh vai ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. hieu van ((bao luc) OR (bao thuc)) tan thanh vai ((cua tre) or (cua te))*.
