To check it out for yourself, please follow these steps: 

1. open the https://docs.couchbase.com/home/server.html page.
2. search for 'docID with regexp type mappings' in the 'search for docs' bar.
3. choose the page pointed in the attached image1 and you'll end up on hanging page image2.

Another note to add here is that, while many of the pages in the above list are used by other pages inside the fts ToC and its subpages, the problem arises when you search for a content like the step 2 above, and you're given with the options which has results that lead to both hanging pages (the one pointed out in image1) and also to a valid one(the option pointed out in image3). It might be uncomfortable to navigate if someone ends up in one of the hanging page results.
