Can you post your query?

Here is my code 

Below is my code to build findFilter

var findFilter = _client
                .BuildFilter<TResult>()
                .And(x => x.MatchTypeHierarchy(typeof(ISearchableContent)) & !(x as ISearchableContent).HideFromSearch.Match(true))
                .Or(x => x.MatchTypeHierarchy(typeof(ExternalUrlBestBet)));

var search = _client.UnifiedSearchFor(query)
                .Track()
                .Filter(findFilter)
                .Skip((page - 1) * itemsPerPage)
                .Take(itemsPerPage);

And the code to return results from search is 

var searchResult = search
                    .ApplyBestBets()
                    .Track()
                    .OverrideCurrentLanguage(Language.None)
                    .GetResult(new HitSpecification());

Thanks,

I checked one of our sites and a ExternalBestBet looks like that in our index as well. Do you get the hit to show if you remove the .Filter() call?

Thanks Johan, I get hits with filters on as shown on my code above, however the point it fails is when I am trying to convert the search Results into PageData, to get meaning information to display it on search page.

Here is my code 

var searchResult = search
                    .ApplyBestBets()
                    .Track()
                    .OverrideCurrentLanguage(Language.None)
                    .GetResult(new HitSpecification());

The above code returns hit, the point it fails is on below code

var results = searchResult
                    .Select(result => result.GetOriginalObject<TResult>())
                    .ToList();

Following is the implementation for GetOriginalObject which is an searchextension. For externalBestBet the OriginalObjectGetter is null, and hence it cannot find the Original Object.

public static T GetOriginalObject<T>(this UnifiedSearchHit hit)
        {
            if (hit.OriginalObjectGetter == null) 
                return default(T);

            var original = hit.OriginalObjectGetter.Invoke();

            if (original is T)
                return (T) original;

            return default(T);
        }

There is a bug raised for Original Object Getter being null , https://world.episerver.com/Modules/Forum/Pages/Thread.aspx?id=150369 on 2016, with no solution to it.

Any other thoughts would be greatly appreciated.

Thanks,

I think an external best bet won't have an original object like that. At least it won't be convertible to PageData but probably just a minimal ISearchContent/UnifiedSearchHit.

Thanks for that Johan, finally implemented with the minimal info from unifiedsearchhit resultset.
