+Cypher prevents getting conflicting results from `MERGE` when using patterns that involve xref:schema/constraints/create-constraints.adoc#create-property-uniqueness-constraints[property uniqueness constraints].
 In this case, there must be at most one node that matches that pattern.
 
 For example, given two property node uniqueness constraints on `:Person(id)` and `:Person(ssn)`, a query such as `MERGE (n:Person {id: 12, ssn: 437})` will fail, if there are two different nodes (one with `id` 12 and one with `ssn` 437), or if there is only one node with only one of the properties.

 If a clause returns no results, it will effectively end the query as subsequent clauses will have no data to execute upon.
