Hi Ed,
The Freebase Suggest code is actually Open Source here:
https://github.com/freebase/freebase-suggest/blob/master/src/suggest.js
But the Javascript code expects a Search service api that takes
parameters. The original Freebase Search service api was a mashup of
Lucene, Solr, Python and Javascript if I recall correctly from the Freebase
engineers discussions on the old mailing list. Anyways, Wikidata or
yourself would have to create such a service. But it looks like one
already exists that powers Wikidata's Search...its just not the best and it
needs token refinement and other stuff from my experiments with it.
Magnus Manske has done a reconciliation service for Wikidata
