Chris Male commented on SOLR-773:
---------------------------------

>From my experience more than just a FunctionQuery is required for LocalSolr to 
>be efficient.  Without the Cartesian tier information that is added by the 
>UpdateProcessor, you will have to calculate the distance for every single 
>document in our index.  The great circle distance calculations are actually 
>quite expensive and when multiplied by say 1 million documents, the query time 
>will become around 2 or 3 seconds.  If you then repeat the calculation again 
>for sorting on distance, then the time will be even worse.  Therefore it seems 
>necessary to include some way to reduce the number of distance calculations 
>that are done.

> Incorporate Local Lucene/Solr

> Local Lucene has been donated to the Lucene project.  It has some Solr 
> components, but we should evaluate how best to incorporate it into Solr.
