Hey,

Find version 13.0.5

I am having two versions of the same code, one using ThenBy with an int (SortIndex) and the other using ThenBy with a string (Name). Both are searching an ISearchable, implemented by all page types (_findClient.Search() is used) and Name is defined in the interface (inherited essentially by PageData), same with SortIndex.

Order by Name works:

                    result = query
                        .OrderBy(q => q.Name)
                        .GetContentResultSafe(searchCacheSettings, cacheForEditorsAndAdmins);

Then by SortIndex works:

                    result = query
                        .OrderByDescending(q => q.Ranking)
                        .ThenBy(q => q.SortIndex)
                        .GetContentResultSafe(searchCacheSettings, cacheForEditorsAndAdmins);

Then by Name works locally, but not in integration environment:

                    result = query
                        .OrderByDescending(q => q.Ranking)
                        .ThenBy(q => q.Name)
                        .GetContentResultSafe(searchCacheSettings, cacheForEditorsAndAdmins);

The error I get by default is the following:

ReduceSearchPhaseException[Failed to execute phase [query], [reduce] ]; nested: ClassCastException; 

Then, I found this post related to OrderBy: https://world.episerver.com/blogs/Son-Do/Dates/2018/7/sorting-issue-in-episerver-find-13-0-1/

Overload of ThenBy with IgnoreUnmapped:true gives the same exception, overload with ThenBy with IgnoreUnmapped:false gives (in a really long error):

Parse Failure [No mapping found for [Name$$string.sort] in order to sort on]];

Any ideas?
