What does "a more exact prefix" mean? Ignoring case sensitivity? Soundex

You should maybe tell more exactly how the api looks that swank expects.
For really efficient matching you'll need to build some form of trees
(tries, binary trees, or at least some sorted vectors), but on one hand
swank might already contain those algorithms (I suppose you're porting
the one for Scheme 48?), and if it doesn't, I think you could also get
by with just walking the table vector and looking at every symbol
string, if it's only for tab completion and similar functionality which
is only checking the symbols at most once per each user input.
(filter (lambda (v) (and (symbol? v) (##global-var? v))) (vector->list
