title: How to implement suggest completion with NEST 6.1.0?
body: <p>So far I have this (for indexing):</p>
  
  <pre><code>var createIndexResponse = await elasticClient.CreateIndexAsync(indexName, c =&gt; c
      .InitializeUsing(indexConfig)
      .Mappings(m =&gt; m
          .Map&lt;ElasticsearchModel&gt;(mm =&gt; mm
              .Properties(
              p =&gt; p
              .Completion(cp =&gt; cp
                  .Name(elasticsearchModel =&gt; elasticsearchModel.StringTest)
                  .Analyzer("simple")
                  .SearchAnalyzer("simple")
              )
              .Text(t =&gt; t.Name(elasticsearchModel =&gt; elasticsearchModel.StringTest).Analyzer("customAnalyzerLowercaseSynonymAsciifolding"))
              )
          )
      )
  );
  </code></pre>
  
  <p>I got to this with the help of this post (but I'm not sure if this is correct as I think that I'm missing some properties to set min. suggestion length etc.): <a href="https://stackoverflow.com/a/33796953/7199922">https://stackoverflow.com/a/33796953/7199922</a></p>
  
  <p>Now I can't figure out how to query it to get the suggestion results.</p>
  
  <p>I have googled the git repo like <code>search suggest site:https://github.com/elastic/elasticsearch-net/</code> and checked the documentation but can't find much.</p>
