Hi, I'm not sure what you mean with how to index a group. You basically index all documents, and then group them for the results. To stay on the books example: you index books including information about the author. So each document in the index is a book. But in your result list, you want to display authors. So you group by author.
For the details about how to group, the package documentation ( http://lucene.apache.org/core/4_0_0-ALPHA/grouping/index.html) should cover what you need.
