<!-- The optional sortMissingLast and sortMissingFirst attributes are
currently supported on types that are sorted internally as a strings.
- If sortMissingLast="true" then a sort on this field will cause documents
without the field to come after documents with the field,
regardless of the requested sort order (asc or desc).
- If sortMissingFirst="true" then a sort on this field will cause documents
without the field to come before documents with the field,
regardless of the requested sort order.
- If sortMissingLast="false" and sortMissingFirst="false" (the default),
then default lucene sorting will be used which places docs without the field
first in an ascending sort and last in a descending sort.
