How Can I Sort The WordPress Buddypress Database?

I have a large membership site with thousands of topics, with each topic having dozens to hundreds of comments.

I would like to take these comments and put them in book form but I cannot figure out how to find these topic comments in the WordPress database.

I can find groups, topics, etc. but I cannot find the comments in the database.

Any help is greatly appreciated.

Thanks,

JoAnn
