Examples of org.apache.lucene.codecs.DocValuesProducer$SortedDocsWithField

org.apache.lucene.codecs.DocValuesProducer
A simple implementation of {@link DocValuesProducer#getDocsWithField} that returns {@code true} if a document has an ordinal >= 0
Codecs can choose to use this (or implement it more efficiently another way), but in most cases a Bits is unnecessary anyway: users can check this as they go.

      assert dvProducer != null;
      SortedNumericDocValues dv = dvProducer.getSortedNumeric(fi);
      dvFields.put(field, dv);
      return dv;
