----------------------------------------------

             Summary: Vector search can restrict on clustering keys when 
filtering isn't required
                 Key: CASSANDRA-19544
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-19544
             Project: Cassandra
          Issue Type: Bug
          Components: Feature/Vector Search
            Reporter: Michael Semb Wever
            Assignee: Michael Semb Wever


With a table that has {{primary key((a,b),c,d)}}

a restriction on only the partition works,
e.g. {{where a=. and b=. order by . ann of .}}

but a restriction that also includes a forward sequence of clustering keys 
(i.e. a clustering key restriction that wouldn't require filtering) does not 
currently work.
e.g. {{where a=. and b=. and c=. order by . ann of .}}


It appears that StatementRestriction:321 is a little too greedy.
