Hi,

You can do a search with the regular Nest.ElasticClient. For example:

using Nest;
using Novicell.Examine.ElasticSearch.Model;

            int page = 1;
            int amountPerPage = 20;      
            string search = "texttosearchfor";

            var settings = new ConnectionSettings(new 

        Uri(System.Configuration.ConfigurationManager.AppSettings["examine:ElasticSearch["externalindex"].Url"].ToString())).DefaultIndex("externalindex");
                var client = new ElasticClient(settings);

                SearchDescriptor<Document> searchDescriptor = new SearchDescriptor<Document>();

                searchDescriptor.Index("externalindex")
                    .Take(amountPerPage)
                    .Skip(amountPerPage * (page - 1))
                    .Query(q => q
                                       .Bool(b => b
                                           .Must(mu => mu
                                                .MultiMatch(qs => qs
                                                    .Query(search).Type(TextQueryType.PhrasePrefix)
                                                    .Fields(fs => fs
                                                        .Field("nodeName") // List of properties where you want to search in
                                                        .Field("otherfield1")
                                                        .Field("otherfield2")
                                                    )
                                                ),
                                                mu => mu
                                               .QueryString(qs => qs
                                                   .Query("Asset") // Search for nodes of type 'Asset'
                                                   .Fields(fs => fs
                                                       .Field("__NodeTypeAlias")
                                                   )
                                               )
                                           )
                                       )
                                   )
                                   .Sort(s => s.Asending("nodeName"));

                //Generate search results
                var results = client.Search<Document>(searchDescriptor);

                if (results != null && results.Documents.Any())
                {
                      foreach(var document in results.Documents) {
                          // Use the Umbraco helper to load the document by Id
                          var node = Umbraco.Content(int.Parse(document["Id"].ToString()) );
                      }
                }

I haven't tested so maybe it contains errors or typos but you'll get the idea i guess. Check the documentation for better explanation https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/nest-getting-started.html
