I saw somewhere in the docs a way to do advanced queries with "whitelisting" nodes, but I can't find it now. Can anyone help with a link?
I want to do a path search in that all the nodes share a common property, but for some reason a basic ()-[]-() type query is returning many other nodes in the middle. I can't seem to control the node properties So I thought I would try the more complicated way to do it!
I have a query a bit like:
match path =
(n1)-[*1..4]-(n2)
where
n1.flow = 'BILL'
and n2.flow = 'BILL'
return path
limit 20
so nodes n1 and n2 should only be with BILL flow.
However nodes with other properties are being returned in the path...
afaik the [...] is just for pattern matching on relations, not on intermediate nodes.
So the above is basically like writing
start(bill)-anything-end(bill) where anything is not controlled by the query above.
So whitelisting to specify node properties seems like one approach?
Perhaps I could also grab everything and just manually walk the graph and filter out nodes that don't match.
