When the Book Chapter facet is applied, in multiple searches the majority of top results listed appear as Journal Article format. My understanding is that this is because Journal Articles an Book Chapters are allowed to match and merge, specifically in order to allow merging of serial monographs. However, many of the top results do not appear to be serial monographs, but actual journal articles. This is confusing for users, and the merges may be causing more frustration than good.
