How to perform amazon cloud search with .net code?

I am learning Amazon Cloud Search but i couldnt found any proper code in either c# or java(though i am creating in c# but if i can get code in java then i can try converting in c#).

This is just 1 code i found in c#:http://ift.tt/1EhPgEm.

This is 1 method i found in this code:

 public IResultSet Search(ISearchQuery query)
        {
            AmazonCloudSearchDomainConfig config = new AmazonCloudSearchDomainConfig();
            config.ServiceURL = "http://ift.tt/1JixzkT";
            AmazonCloudSearchDomainClient domainClient = new AmazonCloudSearchDomainClient("AKIAJ6MPIX37TLIXW7HQ", "DnrFrw9ZEr7g4Svh0rh6z+s3PxMaypl607eEUehQ", config);
            SearchRequest searchRequest = new SearchRequest();
            List<string> suggestions = new List<string>();
            StringBuilder highlights = new StringBuilder();
            highlights.Append("{\'");

            if (query == null)
                throw new ArgumentNullException("query");

            foreach (var field in query.HighlightedFields)
            {
                if (highlights.Length > 2)
                {
                    highlights.Append(", \'");
                }

                highlights.Append(field.ToUpperInvariant());
                highlights.Append("\':{} ");
                SuggestRequest suggestRequest = new SuggestRequest();
                Suggester suggester = new Suggester();
                suggester.SuggesterName = field.ToUpperInvariant() + "_suggester";
                suggestRequest.Suggester = suggester.SuggesterName;
                suggestRequest.Size = query.Take;
                suggestRequest.Query = query.Text;
                SuggestResponse suggestion = domainClient.Suggest(suggestRequest);
                foreach (var suggest in suggestion.Suggest.Suggestions)
                {
                    suggestions.Add(suggest.Suggestion);
                }
            }

            highlights.Append("}");

            if (query.Filter != null)
            {
                searchRequest.FilterQuery = this.BuildQueryFilter(query.Filter);
            }

            if (query.OrderBy != null)
            {
                searchRequest.Sort = string.Join(",", query.OrderBy);
            }

            if (query.Take > 0)
            {
                searchRequest.Size = query.Take;
            }

            if (query.Skip > 0)
            {
                searchRequest.Start = query.Skip;
            }

            searchRequest.Highlight = highlights.ToString();
            searchRequest.Query = query.Text;
            searchRequest.QueryParser = QueryParser.Simple;

            var result = domainClient.Search(searchRequest).SearchResult;

            //var result = domainClient.Search(searchRequest).SearchResult;

            return new AmazonResultSet(result, suggestions);
        }

I have already created domain in amazon cloud search using aws console and uploaded document using amazon predefine configuration option that is movie Imdb json file provided by amazon for demo.

But in this method i am not getting How to use this method like if i want to search Director name then how do i pass in this method as because this method parameter is of type ISearchQuery.

So if any body have successfully manange to run this project then please do post your code or any link to download that running project or if some other code for cloud search then please do post here so that it can help me and others too.
