• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky danh ca hoi. hieu ((ve cac) or (va cac)) cach ban lanh hoi ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky danh ca hoi. hieu ((ve cac) OR (va cac)) cach ban lanh hoi ((cua triet) OR (va triet)).
