1. you probably don't need bi-directional relationships, one is good enough.
2. one way to get the subgraphs is to get one node of each sub-graph and return all paths for that node up to a certain length. MATCH (n:Node) where n.name IN ["foo", "bar"] MATCH path = (n)-[*..5]-() UNWIND nodes(path) as node RETURN n, collect(distinct node) as nodes 3. you can also use the path-expand <https://neo4j-contrib.github.io/neo4j-apoc-procedures/#_graph_algorithms> and clustering algorithms in the APOC procedure library On Tue, Apr 11, 2017 at 11:17 AM, Kai Wang <[email protected]> wrote: > Hi,all, > > I'm using neo4j and I build a large graph that has a lot of subgraph.
