Used to indicate that a particular string property should support sorting. What this typically means is that
for ElasticSearch an additional 'raw' field is added that stores the un-analysed value. This un-analysed value
can be used for sorting etc and the original field used for text searching.


For example, customer name and product name are good candidates for marking with @DocSortable.
