Hi all, I hope to not bother you, but I think I'm writing to the only mailing list that can help me with my question.
I am writing my master thesis about Geographical Information Retrieval (GIR) and I'm using Solr to create a little geospatial search engine. Reading papers about GIR I noticed that these systems use a separate data structure (like an R-tree http://it.wikipedia.org/wiki/R-tree) to save geographical coordinates of documents, but I have found nothing about how Solr manages coordinates. Can someone help me, and most of all, can someone address me to documents that talk about how and where Solr saves spatial informations? Thank you in advance Matteo
