Hi Trejkaz,
My best guess would be to look at
https://github.com/apache/lucene-solr/blob/7f13105fbe0023771b581c0423df7eaa6a76335e/lucene/spatial/src/java/org/apache/lucene/spatial/geopoint/document/GeoPointField.java
and
https://github.com/apache/lucene-solr/blob/7f13105fbe0023771b581c0423df7eaa6
First I have to ask why not use something much more recent? 7.5 comes to mind.
There’s not enough information here to say anything at all about what your
problem might or might not be. “It doesn’t work” provides little to diagnose.
