AutoComplete Posted Tags


(Pavankrishna116) #1

I have an Object in that I have a field Name Tags of type string.

Ex: "Dubai,India, Australia"

I implemeted AutoComplete for this, if I try to search Dubai i.e; Dub will Dubai be shown as a autocomplete tag or the complete "Dubai,India, Australia" will be shown.

public async Task<List<Tag>> Autocomplete(string query)
        {
            var response = await this.client.SearchAsync<BlogPost>(sr => sr
                .Suggest(scd => scd
                    .Completion("tag-completion", cs => cs
                        .Prefix(query)
                        .Fuzzy(fsd => fsd
                            .Fuzziness(Fuzziness.Auto))
                        .Field(r => r.Tags))));

            List<Tag> tagSuggestions = ExtractAutocompleteSuggestions(response);
            return tagSuggestions;

        }

 private List<Tag> ExtractAutocompleteSuggestions(ISearchResponse<BlogPost> response)
        {
            List<Tag> results = new List<Tag>();
            var suggestions = response.Suggest["tag-completion"].Select(s => s.Options);
            suggestions.ToList().ForEach(s =>
            {
                results.AddRange(s.Select(opt => new Tag
                {
                    Tags = opt.Source.Tags
                }));
            });
            return results;
        }

This is the code that I Implemented for the Model brlow.
public class BlogPost
{
public string BlogId { get; set; }
public string Content { get; set; }
[Completion]
public string Tags { get; set; }
public DateTime PostedDate { get; set; }
public string Category { get; set; }
[Text]
public string Title { get; set; }
}
