I use SCOPUS or Web of Knowledge to search papers. What I need to do is to sort the result in a descending order of number of citations. SCOPUS and W_of_K both provide this feature.
But I further need to confine those citations only in a specific field. For example, statistics paper can be cited in another statistics paper or in a medicine paper. What I'm interested in is how many times this paper is cited in another statistics paper.
Using scopus and Web of science, I can see all the papers that cited this paper and then confine to a specific field. But I have to do this for all papers one by one. Thus I wonder if there is any search engine that can to this automatically.
