Frequently plumbing is easier to operate on a record rather than a set of records. Most of us will resort to some kind of "sipping pipeline" that operates on such a single set (rather than a stream of sets).
If you need something that will look at two adjacent records, it sometimes helps to do this: | dup | drop | join , , | Now it's easy to remove the record that has "apple prune" since that represents an apple followed by a prune. After you removed that, you use a "spec w1" will get you the single item per record again. Alternative would be this: | o: if between /apple/ 2 | pick w1 <> /prune/ | o: | Clearly if you know there will be only one apple or one prune, things get way easier... Rob
