Currently, it appears that the Recommendations tool within Fin > Analyze only considers Snippets and public articles (i.e. public synced webpages), but not internal articles. We hold many of our Fin resources as synced Guru pages, which are considered internal articles, so the recommended snippets are not able to consider what already exists there. The Recommendations tool would be so much more useful if it considered all of what Fin can actually use when constructing answers.
Here’s what Fin shared with me when I asked why internal articles weren’t showing - thanks for considering!
Internal articles that are accessible to Fin are not used when generating the recommendations in Fin > Analyze. Recommendations are generated by comparing failed Fin responses to successful human replies, and they’re only generated from your public articles and snippets (not internal articles). That’s why you’ll only see Snippets as “related content” in those recommendations, even if you’ve enabled internal articles for Fin to use in answers.
