Getting top n records for each group in neo4j

Question

I need to group the data from a neo4j database and then to filter out everything except the top n records of every group.

Example:

I have two node

Answer 1

Use LIMIT combined with ORDER BY to get the top N of anything. For example, the top 5 scores would be:

MATCH (node:MyScoreNode) 
RETURN node
ORDER BY node.score DESC
LIMIT 5;

The ORDER BY part ensures the highest scores show up first. The LIMIT gives you only the first 5, which since they're sorted, are always the highest.
