Re: Port of Custom value source from v4.10.3 to v6.1.0
Use the docValues interface by calling getSortedSetDocValues on the
leaf reader. That will either
1) use real docValues if you have indexed them
2) use the FieldCache to uninvert an indexed field and make it look
like docValues.

Use getSortedDocValues for a single-valued field, or
getSortedSetDocValues for multi-valued.

Many Thanks Yonik, I will try that.
For my understanding, what is the difference between SortedSetDocValues
getSortedSetDocValues(String field) and SortedDocValues
getSortedDocValues(String field) ?
