Hello,
The docs at http://jena.apache.org/documentation/query/negation.html
Say that "UNSAIDis an alias for NOT EXISTS"
I wasn't familiar with that keyword so gave it a try at sparql.org and got:
Error 400: Parse error:
# Names of people who have not stated that they know anyone
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
SELECT ?name
WHERE { ?x foaf:givenName ?name . UNSAID { ?x foaf:knows ?who } } Lexical error at line 5, column

Is this a documentation bug?
Yes. Fixed (in staging).

It ought to mention MINUS as well.
