Neo4j Cypher Unknown Error - neo4j

Question

So I created a date dimension from this article
a link
I modified it and added datestamp to Day node which is Month/Day/Year (string)
I added indexes on Year.year, Month.month, Day.day && day.datestamp
When I run this query:
MATCH p=(day2:Day {datestamp:'1/1/2015'})-[:NEXT*]->(day {day:2})
return length(p)
limit 5
It takes 1667 ms to execute
When I modify the query to this:
MATCH p=(day2:Day {datestamp:'1/1/2015'})-[:NEXT*]->(day {datestamp:'1/2/2015'})
return length(p)
After it runs for about a minute, it ends in the Unknown Error message.
My schema is:
Indexes
ON :Day(day) ONLINE
ON :Day(datestamp) ONLINE
ON :Month(month) ONLINE
ON :Year(year) ONLINE
No constraints
Any ideas what I'm doing wrong?

Answer 1

I think I figured it out.
Looks like the 1st query that runs 1667ms only runs and completes because of limit 5, it finds 5 records and stops further execution.
While the other keeps going and going until it runs out of juice.
I think solution in this case is constraint that indicates datestamp is unique which should prevent further execution.
Still interesting, considering there's about 2600+ records connected with HAS_NEXT so traveling through those relationships shouldn't be taking this long to find out that there's only 1 record that matches that query.
