Feedback:
You conduct a subject search by entering a subject heading, such as a topic or keyword into the search field. The subject names have hyperlinks so that we could expand the search by clicking on them or could also click on the author's name or on the journal. Restrictions to the search will place limitations on the subject search in an electronic database, but are not typed in to initiate the search. The ancestry approach ("footnote chasing"), in which citations from relevant studies are used to track down earlier research on which the studies are based (the "ancestors") and the descendancy approach, finding later studies that proceeded from an early study, are other approaches to research, different from the subject search.
