// create initial nodes
WITH ['Joe', 'Ken', 'Lou'] AS names, [1,2,3,4,5] AS ids
UNWIND names AS name 
UNWIND ids AS id
CREATE(p:Person{name:name, id:id})
RETURN p
;

// create new 'same name' nodes with relationship
MATCH(p:Person)
WITH COLLECT(p) AS persons
UNWIND persons AS person
CREATE(p:Person{
      name: person.name
    , id:   person.id + 100
})-[:SAME_NAME]->(person)
RETURN *

创建操作不关心节点是否已经存在。除非您有唯一索引，否则它将创建一个新节点。请尝试以下查询;

MATCH (p:Person) WHERE p.name = "Jose"
//collect all persons with name: Jose
WITH collect(p) as persons
//for every jose in the collection persons, pick the first jose and  do a connection to every other jose in the list
FOREACH (i in range(0, size(persons) - 2) |
 FOREACH (node1 in [persons[i]] |
  //this is the other jose on the list
  FOREACH (node2 in [persons[i+1]] |
   CREATE (node1)-[:SAME_NAME]->(node2))))

FOREACH类似于for循环，我们对列表进行迭代，然后创建关系。
