You can create secondary indexes on node fields using the INDEX keyword. For enforcing uniqueness constraints, see Unique Indexes. To create a secondary index, use the INDEX keyword:

N::NodeType {
  INDEX field1: String,
  field2: U32
}

This internally creates a table for the indexed field. To query a node by the indexed field, you can use object syntax:

QUERY getByIndex(index_field: String) =>
    node <- N<User>({field1: index_field})
    RETURN node

Note: You can currently only use indexing with nodes. Indexing for vectors is not supported yet.
