Examples of org.apache.lucene.index.SortedSetDocValues.nextOrd()

org.apache.lucene.index.SortedSetDocValues.nextOrd()
Returns the next ordinal for the current document (previously set by {@link #setDocument(int)}. @return next ordinal for the document, or {@link #NO_MORE_ORDS}. ordinals are dense, start at 0, then increment by 1 for the next value in sorted order.
