Neo4j - Paths having all nodes with specific label (Operations on labels)

I want to retrieve paths between nodes with constraint on node label. All nodes in the path should hold a specific label. "amps" is my label and My query:

MATCH p=(a:amps{word:"review"})-->()-->()-->(b:amps{word:"nothing"}) 
RETURN p

In the above query, I have two intermediate nodes. Now, I want these two nodes should also hold the label "amps".

How to make comparisons on labels?

If ALL the nodes in the path should have the amps label and with you current query you can do this in two ways :

1) Specify the labels in the () :

MATCH p=(a:amps{word:"review"})-->(:amps)-->(:amps)-->(b:amps{word:"nothing"}) 
RETURN p

2) Specify it with the ALL predicate :

MATCH p=(a:amps{word:"review"})-->()-->()-->(b:amps{word:"nothing"})
WHERE ALL ( n IN nodes(p) WHERE "amps" IN labels(n) )
RETURN p
