I think because your search is fairly general, you're seeing a list of threads containing the keyword that looks almost the same as the original list of all threads in the Floor Finishes subforum.
Another option you can try is to click on the Search drop-down in the top toolbar and use the Google search, which lets you use Google search syntax and searches the entire site, and it returns a different view that gives you a preview of what's in the post or thread that it found.
