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 changing lucenes spatial implementation. See http://www.mail-archive.com/d...@lucene.apache.org/msg03593.html and http://www.mail-archive.com/d...@lucene.apache.org/msg09654.html. Mainly due to the sinusoidal projection. (and if you are interested, I did Mikes spatial example with Lucene 3.0.2 and in Scala http://blog.fakod.eu/2010/11/02/spatial-lucene-example-in-scala/) -- Christopher twitter: @fakod blog: http://blog.fakod.eu On Sat, Nov 13, 2010 at 11:05 PM, Peter Neubauer < peter.neuba...@neotechnology.com> wrote: > Hi there, > I just tried the examples for searching spatial with Lucene at > http://develop.nydi.ch/2010/10/lucene-spatial-example/ > > I am wondering if this still fits into the current Lucene framework > integration, so we could add spatial indexing for simple Nodes with > lat/lon properties into the existing index component, or simply have > another (spatial) index backed by neo4j-lucene-index and exposed > through the index framework?
