Google Scholar advertises itself as "a simple way to broadly search for scholarly literature." They claim that from their scholar site,"you can search across many disciplines and sources: peer-reviewed papers, theses, books, abstracts and articles, from academic publishers, professional societies, preprint repositories, universities and other scholarly organizations." The key is similar to other searches so it's only as good as the parameters you define (year, topic, etc.). You can find a wide range of recent SLP articles on Google Scholar.

The tools on the left hand menu on Google's information page are helpful and provide advanced search tips, support for Libraries and Publishers.
