Here we describe some rarely used Cypher commands for Neo4j that are needed from time to time:
### Index And Contraint Commands
### Index And Constraint Commands
If indexes or constraints are missing or not set correctly, the browser search will not work or the database seed for development will not work.
If indices or constraints are missing or not set correctly, the browser search will not work or the database seed for development will not work.
The indexes and constraints of our database are set in `backend/src/db/migrate/store.js`.
The indices and constraints of our database are set in `backend/src/db/migrate/store.js`.
This is where the magic happens.
It's called by our `prod:migrate init` command.
This command initializes the Admin user and creates all necessary indexes and constraints in the Neo4j database.
