Re: [Neo4j] Spatial search using Lucene-spatial?

Hi, I think Lucene provides a simple way to do distance queries. The limit is, that you can use only points (and a circle to define a distance). No interception with lines, polylines or stuff like that is possible. If you do not need it - fine... BTW: There is currently a discussion about
