Adobe’s IFilter PDF

I had been using Adobe’s IFilter PDF version 5.0 to allow searching on my Intranet for PDF files. Since a lot of these files are images, I updated the document properties “Title, Author etc” and had my indexing service properties search these field. The search works fine, when I enter a title or author, I get the results but my results page only shows the title, nothing else. When I was using v5.0, it showed all properties. Does anyone know if the new PDF filter has new names for the PDF fileds (instead of DocTitle, DocAuthor…maybe DocTitle and something else?) Thanks
