How can I find the total hits for an Elastic NEST query?

In my application I have a query which brings limits the number of hits returned to 50 as follows

            var response = await client.SearchAsync<Episode>(s => s
                .Source(sf => sf
                     .Includes(i => i
                         .Fields(
                             f => f.Title,
                             f => f.PublishDate,
                             f => f.PodcastTitle
                         )
                     )
                     .Excludes(e => e
                         .Fields(f => f.Description)
                     )
                 )
                .From(request.Skip)
                .Size(50)
                .Query(q => q 
                    .Term(t => t.Title, request.Search) || q
                    .Match(mq => mq.Field(f => f.Description).Query(request.Search))));

I am interested in the total number of hits for the query (i.e. not limited to the size), so that I can deal with pagination on the front-end. Does anyone know how I can do this?

You are looking for Total property on the search response object. Have a look.

So in your particular case that will be response.Total.

For those who are working on indices with more than 10000 documents, Elasticsearch will calculate total hits up to 10000 by default. To get around that, include .TrackTotalHits(true) in your query: 

var resp = client.Search<yourmodel>(s => s
    .Index(yourindexname)
    .TrackTotalHits(true)
    .Query(q => q.MatchAll()));
