   [query as cts.query?]
) as Sequence

Summary

This function returns database nodes backing given triples. Any given cts:triple may be backed by zero, one, or multiple database nodes.

Parameters
triples	The triples to locate.
options	Matching options. Valid options include: = Specify equality matching (following the rules of the $operator argument to cts:triples). sameTerm 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). all Specify to return all triple-backing nodes, no matter where or in what format they occur in MarkLogic 7, only `sem:triple` elements are recognized as triples). If this option is not specified, only `sem:triple` elements found in documents that have the root element of sem:triples will be returned. quads Specify to examine the graph component in the passed in `sem:triples` and use it to match.
query	A cts:query to limit the scope of nodes returned.

Example

// Find the URIs of all documents containing a specified triple
const sem = require('/MarkLogic/semantics');

const triple = sem.triple(
  sem.iri('http://dbpedia.org/resource/Judith_Massare'), 
  sem.iri('http://www.w3.org/1999/02/22-rdf-syntax-ns#type'), 
  sem.iri('http://xmlns.com/foaf/0.1/Person'));

var results = [];
for (const node of sem.databaseNodes(triple)) {
  results.push(xdmp.nodeUri(node));
}
