The paths matched by a xref:patterns/fixed-length-patterns.adoc#path-patterns[path pattern] can be restricted to only the shortest (by number of hops) by including the keyword `SHORTEST k`, where `k` is the number of paths to match.
The paths matched by a xref:patterns/fixed-length-patterns.adoc#path-patterns[path pattern] can be restricted to only the shortest (by number of hops) by including the keyword `SHORTEST k`, where `k` is the number of paths to match, and can be either an `INTEGER` literal or a parameter which resolves to an `INTEGER`.
For example, the following example uses `SHORTEST 1` to return the length of the shortest path between `Worcester Shrub Hill` and `Bromsgrove`:
