Restaurant Recommendation GraphGist

Restaurant Recommendations

We want to demonstrate how easy it is to model a domain as a graph and answer questions in almost natural language.

Graph Based Search and Discovery is prominent a use-case for graph databases like Neo4j.

Fetch a Tree with Neo4j

Fetch a Tree with Neo4j

Today I came across a really interesting StackOverflow question:

Given a forest of trees in a Neo4j REST server, I`m trying to return a single tree given the root vertex. Being each tree quite large, I need a de-duplicated list of all vertices and edges in order to be able to reconstruct the full tree on the client side.
