Whats the advantage of using more files?
fyi If you wanted to do this, you can abuse PerFieldDocValuesFormat
today to do it, e.g.:
iwc.setCodec(new Lucene42Codec() {
final DocValuesFormat group1 = new Lucene42DocValuesFormat();
final DocValuesFormat group2 = new Lucene42DocValuesFormat();
...
@Override
public DocValuesFormat getDocValuesFormatForField(String field) {
if (field in some list) {
return group1;
} else {
return group2;
} ...
}
});
