Resume database software will usually have some form of automatically matching applicants to job orders or positions. Gopher's recruiting software has automated matching in several forms and matches applicants from two perspectives.  When you use the phrase executive search software the recruiter usually has the client perspective.

Client perspective matching is of course client centric.  The recruiter focuses on the client and the assignment or job order.  The applicants are the deliverables for measuring success or failure.  The notes, conversations, meetings interviews, reference checks all relate to the product the recruiter is delivering to the client.

Applicant perspective matching is applicant centric. The recruiter's focus is on the applicant.  The deliverables are the jobs the recruiter can qualify the applicant for.  This is the very old agency concept and seldom used.  However an applicant perspective approach is a very good way to do some client marketing.  We will get back to client marketing later.

Being able to flip from client perspective to applicant perspective in an invaluable tool for recruiters because flipping opens new channels and new opportunities.  Going down the client perspective path leads to tunnel vision, which I believe is death to the recruitment process.

Staffing software by Blackdog will auto match when importing resumes, when clicking from the position tab to the resume tab, when clicking from the resume to the position tab, and from the 'matches' menu.
