Vertex Centric Queries

Vertex Centric Queries

Overview

Vertex centric queries allow you to take advantage of primary keys

We've tried to stick closely to the Blueprints spec for vertex centric queries.

Examples

# 10 things that Jon likes or hates
jon.query().labels(Likes, Hates).limit(10).direction(OUT).vertices()
blake.query().labels(Teaches).direction(OUT).edges()
eric.query().labels(Drinks).limit(1000).direction(OUT).vertices() # returns too many beers - need to put a limit
blake.query().labels(EnrolledIn).interval('enthusiasm', 2, 9).vertices()

We can also filter by ranges

jon.query().labels(Attends).has('gpa', 3.0, GREATER_THAN).direction(OUT).vertices()

We can go in any direction - IN, OUT, BOTH are all supported.

blake.query().labels(LIKES).direction(IN).edges() # returns a lot of edges, everyone likes blake
eric.query().labels(LIKES).direction(BOTH).vertexIds() # anyone eric likes, and who likes him
