Examples of org.jboss.dna.graph.query.model.FullTextSearch

org.jboss.dna.graph.query.model.FullTextSearch
A constraint that evaluates to true only when a full-text search applied to the search scope results in positive findings. If a property name is supplied, then the search is limited to the value(s) of the named property on the node(s) in the search scope.
