 |**numeric_partition_sort_mode_within_level** | How to sort the values of numeric metadata to create the numeric partitions. |** unicode:** Sort using the Unicode Collation Algorithm.

E.g. 10 would sort before 9. \\ **alphanumeric:** (Default) Sort using a more natural sort, where digits are treated as numbers and sorted numerically. E.g. 10 would sort after 9.|
 |**numbers_first** | Sort the numbers to the start of the list (By default, metadata values starting with numbers are sorted at the end).|  |
