Search in the modding forum(i.e. where the DT thread has been all along), and you get two of those results. The first links to a page with a link to information, but not to the post with the actual link. (This, incidentally, is what I got as the first hit on the more general search - again, not the thread with the link. Scrolling down from where it lands gets "sorry, it's not supported".) The second hit links to the DFHack version of DT.
Even in the more general search, the excerpts of the useful posts have enough code in them to be intimidating if you don't already know that that's precisely what you need.
The point: The search tool is not the holy grail that some people think it is. In this case especially, it's possible to shoot yourself in the foot by trying to use an appropriately defined search - the useful hits are buried in FOTF threads in General Discussion(and if you were to tell someone "it's posted in this thread" regarding the 1000-page monstrosity that one of them is in, you would deserve to be slapped). Combine that with the length of even this thread, and if you don't already know exactly what you're looking for, it's easy to get discouraged and give up.
I say all this because one of the strongest things about DF, in my experience, has been a friendly and helpful community. Anything that makes it more hostile and insular, thus, weakens the experience.
