I'm getting ready to start a project where I will be building a recommendation engine for restaurants. I have been waffling between neo4j (graph db) and mongodb (document db). my nodes/documents will be things like restaurant and person. i know i will want some edges, something like person->likes->restaurant, or person->ate_at->restaurant. my main query, however, will be to find restaurants within X miles of location Y.
if i have 20 restaurant's within X miles of Y, but not connected by any edges, how will neo4j be able to handle the spatial query? i know with mongodb i can index on lat/long and query all restaurant types. does neo4j offer the same functionality in a disconnected graph?
when it comes to answering questions like, 'which restaurants do my friends eat at most often?', is neo4j (graph db) the way to go? or will mongodb (document db) provide me similar functionality?

It offers high scalability, reliability, and performance. MongoDB also uses text-based indexes for full-text queries, but the search is slow, and the search server does not provide tokenizers and analyzers like Elasticsearch does.
Additionally, Neo4j has scalability weaknesses related to scaling writes, hence if your application is expected to have very large write throughputs, then Neo4j is not for you.
The World's Leading Organizations Rely on Neo4j. With more than 950 enterprise customers, Neo4j is the world's leading provider of scalable graph technology, enabling connected data applications for more than 75% of the Fortune 100.
Neo4j Spatial introduces a Spatial RTree (or other means) index that is part of the graph itself. That means, even disconnected domain entities will be found via the spatial search, if you index them (that is relationships will connect the Spatial index to the Restaurants). Also, this is flexible enough that you can combine the Raw BBox search in the RTree with other things like check on the restaurants categories in the same go, since you can hop out and in the different parts of the graph.
This way, neo4j Spatial is supporting the full range of search capabilities that you would expect form a full Topology, like combined searches and searches on polygons with holes etc.
Be aware that Neo4j Spatial is in 0.7, so be gentle and ask on http://groups.google.com/group/neo4j/about :)
