SortedTermFreqIteratorWrapper(TermFreqIterator source)
Creates a new sorted wrapper, using BytesRef.getUTF8SortedAsUnicodeComparator() for
sorting. |

SortedTermFreqIteratorWrapper(TermFreqIterator source,
Comparator<BytesRef> comparator)
Creates a new sorted wrapper, sorting by BytesRef (ascending) then cost (ascending). |
