• Performing a fuzzy search may retrieve terms with similar spellings: nuoc sach y nang xa hoi. hieu ((ve cau) or (ke cau)) ((phuc va) OR (thuc va)) hanh de cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc sach y nang xa hoi. hieu ((ve cau) OR (ke cau)) ((phuc va) OR (thuc va)) hanh de cuu tre.
