Node Querying

Table 1. Functions
Qualified Name	Type	Release
apoc.nodes.isDense - returns true if it is a dense node	`Function`	`APOC Core`
apoc.nodes.connected - returns true when the node is connected to the other node, optimized for dense nodes	`Function`	`APOC Core`
apoc.node.relationship.exists - returns true when the node has the relationships of the pattern	`Function`	`APOC Core`
apoc.node.relationships.exist - returns a map with rel-pattern, boolean for the given relationship patterns	`Function`	`APOC Core`
apoc.nodes.relationships.exist - returns a list of maps where each one has two fields: `node` which is the node subject of the analysis and `exists` which is a map with rel-pattern, boolean for the given relationship patterns	`Function`	`APOC Core`
apoc.node.relationship.types - returns a list of distinct relationship types	`Function`	`APOC Core`
apoc.nodes.relationship.types - returns a list of maps where each one has two fields: `node` which is the node subject of the analysis and `types` which is a list of distinct relationship types	`Function`	`APOC Core`
apoc.node.degree - returns total degrees of the given relationships in the pattern, can use '>' or '<' for all outgoing or incoming relationships	`Function`	`APOC Core`
apoc.node.id	`Function`	`APOC Core`
apoc.node.degree.in - returns total number number of incoming relationships	`Function`	`APOC Core`
apoc.node.degree.out - returns total number number of outgoing relationships	`Function`	`APOC Core`
apoc.node.labels	`Function`	`APOC Core`
apoc.any.properties	`Function`	`APOC Core`
apoc.any.property	`Function`	`APOC Core`
apoc.label.exists - returns true or false related to label existance	`Function`	`APOC Core`

Rel-direction-pattern Syntax:

[<]RELATIONSHIP_TYPE1[>]|[<]RELATIONSHIP_TYPE2[>]|…

Example: 'FRIEND|MENTORS>|<REPORTS_TO' will match to :FRIEND relationships in either direction, outgoing :MENTORS relationships, and incoming :REPORTS_TO relationships.

Table 2. Procedures
Qualified Name	Type	Release
apoc.nodes.get - quickly returns all nodes with these ids	`Procedure`	`APOC Core`
