we're using Solr in our service. Recently, we're working on upgrading Solr to Solr6 & spatial4j-v0.6. But we faced that geospatial data cannot be fed, it's rejected, that has syntax like Circle(lat, lon, d=d).
It seems the syntax is dropped from Solr, but is it really dropped? Since when and why?? I couldn't find official statement that they dropped this syntax.
As for now, I find an option format=LEGACY for the fieldType, then Solr accepting data. But, are there any recommended, proper way to do with Circle()? Should we move to WKT/GeoJSON?
<fieldType
name="location_rpt"
class="solr.SpatialRecursivePrefixTreeFieldType"
spatialContextFactory="org.locationtech.spatial4j.context.jts.JtsSpatialContextFactory"
format="LEGACY"/>
