The result paths that I get with the query

Answer 1

In 2.3.0, use the following:

MATCH path = (start {id:2})<-[*1..]-(end {id:3}) 
WHERE ALL(n in nodes(path) where 
          1 = size(filter(m in nodes(path) where m=n))) 
RETURN start, LENGTH(path) AS length, EXTRACT(p in NODES(path) | p.id), end
ORDER BY length
