Assuming that you need case-insensitive sort, the most straightforward
way to do this would be to index the lowercase family name:
SortedDocValuesField("by_name", new
BytesRef(family.getName().toLowerCase(Local.ROOT))).
It is also possible to implement a custom FieldComparatorSource, but
this will likely be both more complicated and slower.
