We have a search query in which we insert a rather long filter expression using the below method:

public static ITypeSearch<TSource> ExcludeEntryCodes<TSource>(this ITypeSearch<TSource> search, IEnumerable<string> codes) where TSource : IBaseEntry
        {
            if (codes != null && codes.Any())
            {
                var codeFilter = search.Client.BuildFilter<TSource>();
                foreach (var code in codes)

                {
                    codeFilter = codeFilter.And(x => !x.Code.Match(code));
                }
                return search.Filter(codeFilter);
            }
            return search;
        }

Our issue is that if the list of "codes" are to long (around 20), Episerver Find returns a bad request. Any ways of optimizing the request?

In the error message is seems that the request towards Find gets rather verbose. Something like:
