Bill Bell commented on SOLR-2345:
---------------------------------
Here is more info:
id=56
store=43,-96
store=42,-97.5
id=57
store=42,-97
store=41,-95
id=58
store=40,-95
I am trying to do:
http://localhost:8983/solr/select?q=*:*&fq={!geofilt}&pt=42,-97&sfield=store&d=10&sort=geodist()
asc
I want to change geodist() to return id=56 and id=57.
return order:
id=57 {42,-97}
id=56 {42,-97.5}
But when I look at HaversineConstFunction.java "geodist()", it is only looking
at the 2nd value in the multiValue list. So the result is:
id=56 {42,-97.5}
id=57 {41,-95}
id=58 {40,-95}
So I want the algorithm to be for a function on a multiValue="true" field:
1. The geodist() function should check both distances in the multiValue list,
and return the closest (asc) or farthest (desc) distance computed
2. Then it should sort on the distance that is returned from #1
But when I looked at HaversineConstFunction.java and debug it, I cannot find a
way to get both ValueSource. It only seems to return the last one.
Basically I need a method like latVals.doubleVal(doc) to return array of lat
values for a document. The Lucene function to get the field
"store_0_coordinate" only returns one value for the multiValue field.
Once I figure this out, I can see extending all functions to support multiValue
fields by using the #1, #2 above.
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?
