IOW search engines find words by precomputing a hashed "signature" of a document that records roughly which words are in it. This won't fly on a machine with so little RAM, to say the least. (A "page" of the Box's soundtape secondary storage is 2K six-bit letters, enough to fill the vitascreen once. Like a 1960 PDP-1 IOW, the Box has 4K 18-bit words (six pages) of RAM.
