neo4j/cypher: Using a WHERE clause to filter paths by Mark Needham.
From the post:
One of the cypher queries that I wanted to write recently was one to find all the players that have started matches for Arsenal this season and the number of matches that they’ve played in.
Mark sorts out the use of a where clause on paths.
Visualization of a query as it occurs, tracing a path from node to node, slowed down for the human observer, could be an interesting debugging technique.
Will have to give that some thought.
Could also be instructive for debugging topic map merging as well.
Either one would be subject to visual “clutter” so it might work best with a test set that illustrates the problem.
Or perhaps by starting with the larger data set and slowly excluding content until only the problem area remains.
