Basically, I'm trying to implement rules engine in neo4j and I think that
pattern matching would be the right way to find the rule. But I really don't
know how to do that in Cypher or even in PatternMatching.
This is my graph
(customers)---[:applies]--(rules)
Hi there,
Your images are difficult to read on gmail. A gif might help. :)
I'm not quite certain on what is not working. In Cypher, your question would
look something like this:
START rules=(0)
MATCH (subReference
)-[:APPLIES]-(rules)-[:RULE]-(rule)-[r,:LESS_THAN]-(answer)
WHERE r.Threshhold 0
Thanks for the reply, sorry the DatabaseHelper is just my class to get an
index of a node. :)
Will try that soon, Thanks very much.

From the query above I got this error.
org.neo4j.cypher.SyntaxError: string matching regex `(?i)\Qreturn\E'
expected but ` ' found
What does it mean? Thanks :)

Hi!,
I've fixed that issue already, it's because I forgot to load my database up.
But now I got a new error from ExecutionResult
Method threw 'java.lang.UnsupportedOperationException' exception instead
when I debug it.

Hi, I found the error already, but I'm not sure if it's related to the API.
If I use AND in the WHERE clause. It causes the error, but If I use and
it runs ok. :)

Good catch. Fixed in trunk now.
