  It is tempting to see Fodor's concerns as resting on a fallacious argument to the effect that a process must be informationally encapsulated to be computationally tractable. We only need to consider the effectiveness of Internet search engines to see that, thanks to clever indexing techniques, this is not the case. Submit any pair of seemingly unrelated keywords (such as “banana” and “mandolin”) to a Web search engine, and in a fraction of a second it will identify every web page, in a database of several billion, that mentions those two keywords (now including this page, no doubt). But this is not the issue at hand. The real issue, to reiterate the point, is one of relevance. A process might indeed be able to index into everything the system knows about, say, bananas and mandolins, but the purported mystery is how it could ever work out that, of all things, bananas and mandolins were relevant to its reasoning task in the first place.
