Bill Bell commented on SOLR-2345:
---------------------------------
If we can change geodist() and {!geofilt} to work on lat_long multiValues. This
would allow more flexibility. So a person with multiple addresses will be
supported.
I worked on geomultidist() in SOLR-2155. We would just need to support this in
the actual filter to limit the results for the multi value list.
Thoughts?
Thanks.

> Extend geodist() and potentially other functions to support MultiValue fields
> for sorting and scoring.
> sort=geodist() asc
> This should grab the closest point in the MultiValue list, and return the
> distance so that is can be scored.
> The problem is I cannot find a way to get the MultiValue list?
> In function:
> src/java/org/apache/solr/search/function/distance/HaversineConstFunction.java
> VectorValueSource p2;
> this.p2 = vs
> List<ValueSource> sources = p2.getSources();
> ValueSource latSource = sources.get(0);
> ValueSource lonSource = sources.get(1);
> DocValues latVals = latSource.getValues(context1, readerContext1);
> DocValues lonVals = lonSource.getValues(context1, readerContext1);
> double latRad = latVals.doubleVal(doc) * DistanceUtils.DEGREES_TO_RADIANS;
> double lonRad = lonVals.doubleVal(doc) * DistanceUtils.DEGREES_TO_RADIANS;
> etc...
> It would be good if I could loop through sources.get() but it only returns 2
> sources even when there are 2 pairs of lat/long.
> sources:[double(store_0_coordinate), double(store_1_coordinate)]
> How do I extend the sources?
