How do I update an existing document inside ElasticSearch index using NEST?

Question

I am trying to update an existing indexed document. I have indexed tags, title and owners field. Now when the user changes the title, I need to find and update the document

A better solution in Nest 7.x:

 await _client.UpdateAsync(doc.Id, u => u.Index("movies").Doc(new ElasticSearchDoc { Title = "Updated title!" }));
