Detecting potential typos using EXPLAIN by Mark Needham.
Mark illustrates use of EXPLAIN (in Neo4j 2.2.0 RC1) to detect typos (not potential, actual typos) to debug a query.
Now if I could just find a way to incorporate EXPLAIN into documentation prose.
PS: I say that in jest but using a graph model, it should be possible to create a path through documentation that highlights the context of a particular point in the documentation. Trivial example: I find “setting margin size” but don’t know how that relates to menus in an application. “Explain” in that context displays a graph with the nodes necessary to guide me to other parts of the documentation. Each of those nodes might have additional information at each of their “contexts.”
