• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sach y)) nang xa hoi. hieu ve nam thuc ca dan ca cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) nang xa hoi. hieu ve nam thuc ca dan ca cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach y)) nang xa hoi. hieu ve nam thuc ca dan ca cuu tre*.
