When querying search results and wanting to return results without a sort order the query fails:

Suggest that the default OrderBy asc is set to eliminate this

"Each clause has sort criteria, optionally followed by a sort direction (asc for ascending or desc for descending). If you don't specify a direction, the default is ascending. If there are null values in the field, null values appear first if the sort is asc and last if the sort is desc." https://docs.microsoft.com/en-gb/azure/search/search-query-odata-orderby
