As the co-founding CTO of Hotjobs.com, we provided this functionality on the very first version of Hotjobs in 1996, and subsequently ended up purchasing Resumix to provide a very in depth technical solution to allow employers this exact functionality you're describing.
Of course, we had tens of millions of resumes in every possible industry imaginable all searchable through a very robust search interface that did all sorts of fancy lexical analysis and data extraction from random resume formats.
Over the last 13 years, thousands upon thousands of people have been hired through the exact mechanism you're describing.
