• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky ((((nang xa) OR (nang ma))) or (lang xa)) hoi. hieu ve chat xuc va van thai va thieu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((((nang xa) OR (nang ma))) OR (lang xa)) hoi. hieu ve chat xuc va van thai va thieu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((((nang xa) OR (nang ma))) or (lang xa)) hoi. hieu ve chat xuc va van thai va thieu".
• Adding a wildcard symbol may retrieve word variants: su sach ky ((((nang xa) OR (nang ma))) or (lang xa)) hoi. hieu ve chat xuc va van thai va thieu*.
