Sudarshan Gaikaiwari commented on LUCENE-4450:
----------------------------------------------
I am sorry that my talk was confusing. The modifications I made to the WFST
suggester are not for boosting the suggestions by geodistance but to restrict
the suggestions to a particular geographical location. The code to do this is
available here
https://github.com/sudarshang/lucene-solr
Please see
https://github.com/sudarshang/lucene-solr/blob/master/lucene/spatial-suggest/src/java/org/apache/lucene/search/spatial_suggest/WFSTGeoSpatialLookup.java.
I am interested in bring this branch up to date with the current trunk and
contributing it to Lucene.

> Project: Lucene - Core
> Issue Type: Improvement
> Affects Versions: 4.0
> Reporter: Bill Bell
>
> 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).
