SOLR query over specific array list
i am having an array in my SOLR document and i want to access an exact index of this array.
in more detail, i want to go through latitude and longitude arrays, calculate the minimum distance of all those and sort the document by this.
{
"title": "iphone",
"latitudes": [48.5, 48.0, 49.1, ...],
"longitudes": [16.1, 16.3, 17.3, ...]
}
for this i want to calculate the following:
dist1=dist(latitudes[0],longitudes[0], 48.32, 16.43)
dist2=dist(latitudes[1],longitudes[1], 48.32, 16.43)
...
minDist=min(dist1, dist2, ... distN)
i would expect a syntax like beneath but it does not work:
&fl=min(dist.latitudes, dist.longitudes, 48.32, 16.43)&sort=min(dist.latitudes, dist.longitudes, 48.32, 16.43)
and as output i would like to order it by this minDist and add it to the document having the following result:
{
"title": "iphone",
"latitudes": [48.5, 48.0, 49.1, ...],
"longitudes": [16.1, 16.3, 17.3, ...],
"minDist": 456.12
}
the amount of latitudes and longitudes is dynamic.
does anybody have an idea on how to solve this issue? i started SOLR a few weeks ago and i cant find a solution.
thanks in advance!

Why aren't you indexing these points as actual geometric latitude/longitude points? Using min with just the coordinates as Manhattan Distance will not give the correct result for all cases either, so you should really change to a field type suited for spatial data.
