Description
A common Suggester use case is to boost the results by closest (auto suggest the whole USA but boost the results in the suggester by geodistance). Would love to get faster response with that. At the Lucene Revolution 2012 in Boston a speaker did discuss using WFST to do this, but I have yet to figure out how to do it).
