So this is is the "right" way to put a standard search url out on a page, in such a way that the search url conventions are not replicated throughout the lisp code in thousands of "(format nil "~A~?~A=?A+?A..." ...) statements, and so that a change in search string conventions can be easily implemented.

It seems that the note-anchor fn is looking for a URL, but the STANDARD-WRITE-SEARCH-INFO function wants to write to a stream.
Sorry, the right url for documentation is:
http://wilson.ai.mit.edu/cl-http/show-documentation?HTTP%3AEXPORT-URL
If you pass an interned URL to note-anchor, it will write the correct thing in your html.
There is no more convenient way to just make a URL beyond intern-url. So, you could
creaye the search url as an uninterned url and use it as a prototype. You set the search
keys to the desired parameters, recompute the name string, and then pass this to note-anchor.
If a cleaner way to accomplish this springs to mind and this is a frequent activity, we could
add it to the system.
