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

also using Nest 7.x.

If you want to do only a partial update, you can use this method that worked great for me. You must specify "T, K" where T is the full object and K the partial object. Creating a POCO for every partial update is kind of overwork and annoying. For this issue, you can use anonymous object like so

 public bool PartialUpdate(string id, object entity)
 {
     var result = _elasticClient.Update(DocumentPath.Id(id), i => i.Index(_indexName).Doc(entity));

     return result.IsValid;
 }

Im using the Elastic Common Schema, so here is an example of a partial object for the update:

new
{
    Labels = new Dictionary
    {
        { "EscalateTo", alert.AlertState == AlertState.Escalation ? escalationId : "" },
        { "EscalateFrom", alert.AlertState == AlertState.Descalation ? escalationId : "" },
    },
    Event = new
    {
        End = alert.WindowEnd,
        Duration = (alert.WindowEnd - storedAlert.StartTime.Value).Ticks
    }
};
