Indexing large amounts of candidate data, including extracting 'skill' information from CVs, is pretty much a solved problem. It's what my employer's products do.
We also have products that do 'Candidate Matching' - which is exactly what you're talking about here, taking structured requirements for a specific job and then seeing who in the database matches. We normally do it against a recruiter's own local DB, and can do some degree of matching against internet job boards, LinkedIn, that sort of thing.
There was some interest in a product that would index all of the job boards for every UK local authority/council for one client, but that fell through. Going through every company's individual job postings is just impossible, and wouldn't help anyway: in my experience the best jobs are the ones that say 'no agencies', and it's only recruiting agencies who are spending on the kind of software we make.
