CIR-2017-179

In order to support expressing more complex patterns over the graph, a syntax for Regular Path Queries would be desirable. Such a feature should support the following combinations of path patterns:

  • Alternatives (or unions) (either this pattern or that pattern)
  • Sequences (first this pattern, than that pattern)
  • Transitive closure (this pattern repeated multiple times)
  • Grouping of patterns
  • Predicates on node and relationship properties.

Possibly we might also want a way to express any path not matching the given pattern.

I have started working on a proposal for how to bring Regular Path Queries to Cypher. See CIP2017-02-06.
