The `USING INDEX` sub-clause is only for giving Neo4j a hint as to the
index to use. Normally it will work that out for itself, and you shouldn't
need to use it.
In your case, you have two indexes: one on :Person(name) and the other
:Person(job). To use either of those indexes in a query, the C

INDEX clause usage :
Consider three nodes :
:Person {name:"Sylvain", job:"Developper"}
:Person {name:"Philip", job:"Developper"}
