Hello Boris,
Tags are still being worked into search so that they can be available as filters based on the available metadata (tags) embedded in the content. However, there will not be tags for archived content, only net new. The team is still in the process of incorporating all the new content into the search index.
We are working on a concept to boost the ranking of starting pages for topics/products. We may likely use Best Bets (promoted search results) until something automatic is available. This would rely on topic and product specialists to suggest the best target for common queries.
Thanks for your feedback.
Jason
