I suspect your code already runs into one of the big problems that the OP will have-- if OP is looking for the paper that's referenced, rather than things that contain the reference, it's likely to be behind a paywall. The simple "grab the first pdf" is likely to get some combination of papers that reference the paper the OP is looking for, and which may be behind paywalls, or CV's of the authors (which you snagged).
