I had a question from a student on my workshop. "How do you specify the years of experience in a search? (e.g., java developers with 3 to 7 years experience)"
My suggestions were to use the Google numrange in various ways. As an example, you could search on Google for "computer science * 2001..2003" java intitle:resume | inurl:resume
to try to catch their year of graduation (assuming that their major is CS).
