Can't get neo4j to perform on undirected relationships

[clem]

To clarify: Does your query work for small data but not with big data?

Then there is a performance issue.

Try running the query with the PROFILE and look at the plan. If the query doesn't filter out large enough nodes, then you could have a combinatorial explosion which will take a very long time and appear not to come back.

See:

CALL subqueries - Cypher Manual

And this specific example of using a subquery to speed things up.

Slow query with very limited data and boolean = false

Hey all, I'm running up against an unexpectedly slow Cypher query, and I've looked into several other posts but I'm still not sure what to do about my graph to make it more performant. In my query, I'm trying to find "unreserved" siblings of the origin node. Essentially, I want to walk up a :CHILD relationship to the (one) parent node, then find all of that parent's children that are not reserved. My data represents the structure of a document, which has nested levels: Title Subtitle Chapt…
