addIndex: Indexes

In nicolewhite/RNeo4j: Neo4j Driver for R

Description

Add an index to a node label and property key.

Usage

addIndex(graph, label, key)

Arguments

graph	A graph object.
label	A character string.
key	A character string.

Details

An index already exists for any (label, key) pair that has a uniqueness constraint applied. Attempting to add an index where a uniqueness constraint already exists results in an error. Use getConstraint to view any pre-existing uniqueness constraints. If a uniqueness constraint already exists for the (label, key) pair, then it must be true that the index exists as well; adding an index is unnecessary.
