It shouldn't be even cool to an engineer if you get rid of all the abstraction sauce you need to make this appear halfway elegant on a technical level. Web search and local search don't even have the same interface: one takes a string and returns a list of web URLs based on a black box algorithm, the other takes a string along with potential other attributes and returns a list of local files that match a fulltext search. I don't see any meaningful way to calculate a relevance score across both web results and local files. The only reason you'd want to do this IMO is if you're desperate to get traffic to your search engine.
