comment Why is Google so much faster than a hard-drive search?
@Adnan, file system isn't really an "index", just a tree of file names. Searching such tree isn't fast, because it's structure isn't optimized for searching. OTOH google (and databases) uses specific sorted index structures which makes lookup for particular entry lightning fast. Even then, not all searches can benefit from such index and will be slow(er).
