New paper search method.

I really need to limit the number of papers I am going to read. Instead of Proquest by happenstance Proquest was not working this evening so I switched to google scholar. I sent up my preferences for that and managed to learn to export citations from google scholar into RefWorks. I limited my results to the top 20 papers in the search for the first three types of knowledge. I will now before I sleep try to do this again and see if I can not get all the terms searched for with this method.
