I'm currently getting up to speed on a project that includes nearly 1,800 pages of specifications across 3 volumes. The PDFs include dozens of Bookmarks, which can help with navigation, but there are still a lot to scroll through.
While I can search the entire document - or even all 3 documents - for a text value using the current search tools I end up with dozens of hits, depending on my word choice. Being able to search the Bookmarks panel would allow you find the desired section of the document faster, without having to wade through dozens of search hits in the body of the document.
