Examples of org.apache.lucene.util.automaton.CompiledAutomaton.floor()

org.apache.lucene.util.automaton.CompiledAutomaton.floor()
Finds largest term accepted by this Automaton, that's <= the provided input term. The result is placed in output; it's fine for output and input to point to the same BytesRef. The returned result is either the provided output, or null if there is no floor term (ie, the provided input term is before the first term accepted by this Automaton).
