Subject Re: Solr Suggester with Geo?
Date Tue, 10 Nov 2015 09:53:38 GMT
Out of the box the Suggester componenent provides a set of Lookup
implementation to look for the suggestions from the dictionary selected.
Most of the suggestion lookups are FST based ( except the Analysing Infix
one , that relies on an external auxiliary Lucene Index) .

Depending on your requirement you should customise the lookUp
implementation to score the suggestions taking in consideration the
distance.
Customising the "Auxiliary Lucene Index " based look up strategies would be
easier.
Playing with the FST look up would be much more complicated.

Cheers
