• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((tu lang) OR (cu lang)) xa hoi. hieu van cam xuc va ((hanh via) or (anh va)) cua cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((tu lang) OR (cu lang)) xa hoi. hieu van cam xuc va ((hanh via) OR (anh va)) cua cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((tu lang) OR (cu lang)) xa hoi. hieu van cam xuc va ((hanh via) or (anh va)) cua cau".
• Adding a wildcard symbol may retrieve word variants: tu sach ((tu lang) OR (cu lang)) xa hoi. hieu van cam xuc va ((hanh via) or (anh va)) cua cau*.
