In Premeir Elements 8 to search for photographs that do not have a people tag and a created sub-category or keyword tag that has been created under the People tree? I've begun organizing a large amount of photo files and used the people recognition feature but there are a large number of files where the application did not recognize a face. Being able to search for photos that do not have a top tree People category tag or a subordinate would allow those photos to be quickly found so that you can individually tag them. This would also help if you could search/find on any of the categories such as Events, Places, or Other.
Unfortunately, there's no fully automatic way to do this, rs. Sorry.
