com.hp.hpl.jena.graph.query.GraphQuery.addMatch()
Add an (S, P, O) match to the query's collection of match triples. Return this query for cascading. @param s the node to match the subject @param p the node to match the predicate @param o the node to match the object @return this Query, for cascading
