How to find a list of index using Cypher

Question

I've created an INDEX using cypher for my :Person label, but I cannot find any way of printing out a list of indexes or constraints available to my Neo4j system.

Is this something that is doable via Cypher?

Answer 1

In browser you can use :schema or schema in the shell to print out all the indexes and constraints.

Answer 2

As Eve pointed out, you can get labels by calling CALL.Labels(). To get indexes just do:

CALL db.indexes()

Also if you do CALL db. in your neo4j browser you will see all the functions available.

Answer 3

Nope. There's not even a way to list labels:

There are some REST calls for this, and the undocumented schema command in neo4j-shell is handy.

Edit: Update for 3.0 with the new stored procedures!

CALL db.labels()

Answer 4

(Applicable to neo4j version 2.3.1 or later)

To get indexes via REST use this:

curl http://localhost:7474/db/data/schema/index/

In the neo4j console you can run the :schema command to get all indexes & constraints.
