- Specify sameTerm matching (following the rules of the $operator argument to cts:triples) (if neither '=' nor 'sameTerm' are specified, this option gets used by default).
- Specify to return all triple-backing nodes, no matter where or in what format they occur in MarkLogic 7, only
sem:tripleelements are recognized as triples). If this option is not specified, onlysem:tripleelements found in documents that have the root element of sem:triples will be returned.- Specify to examine the graph component in the passed in
sem:triplesand use it to match.
