Neo4j-返回不'；我没有特别的钥匙

我想返回没有特定密钥的节点

MATCH (n:Company) 
with n,keys(n) as keys_set 
WIth n,keys_set, max(size(keys_set)) As maxi 
RETURN n where keys_set < maxi

节点：

A(1:"xa",2:"ya",3:"za")         
B(1:"xb",2:"yb",3:"zb")        
C(2:"yc",3:"zc") 

MATCH (n:Company) 
with n,keys(n) as keys_set 
WIth n,keys_set, max(size(keys_set)) As maxi 
RETURN n where keys_set < maxi

现在，我想返回C节点，因为它没有名为1的键

MATCH (n:Company) 
with n,keys(n) as keys_set 
WIth n,keys_set, max(size(keys_set)) As maxi 
RETURN n where keys_set < maxi

我的做法：

MATCH (n:Company) 
with n,keys(n) as keys_set 
WIth n,keys_set, max(size(keys_set)) As maxi 
RETURN n where keys_set < maxi

匹配（n：公司）
使用n，键（n）作为键集
n，keys_set，max（大小（keys_set））为maxi
返回n，其中键设置MATCH (n:Company)
WHERE NOT EXISTS(n.`1`)
RETURN n

错误：

MATCH (n:Company) 
with n,keys(n) as keys_set 
WIth n,keys_set, max(size(keys_set)) As maxi 
RETURN n where keys_set < maxi

无效输入“h”：应为“i/i”（第1行，第99列（偏移量：98））“将（n:Company）与n匹配，键（n）作为键集与n匹配，键集，最大值（大小（键集））作为最大值返回n，其中键集

MATCH (n:Company)
WHERE NOT EXISTS(n.`1`)
RETURN n
