Answer 1

One approach would be to add tags to the articles when they are listed. One tag would be XYZ. Other tags might describe the article subject.

You can do that in a database. You can have an unlimited number of tags for each article. Then, the "groups" could be identified by one or more tags.

This approach is heavily dependent upon human beings assigning appropriate tags, so that the right articles are returned from the search, but not too many articles. It isn't easy to do really well.
