How can I get the total number of documents found using the Nest?

Question

I do the same request using the nest, and directly in ElastichSearch. When I see direct request, how many documents match request.

  "hits": 
  {
    "total": 1640,
    "max_score": 1,
    "hits": [...]
   }

My query:

 var search = client.Search<RCompany>(s => s.Index("MyIndex")
 .Query(qq => qq
 .Filtered(m => m.Filter(f => f.Bool(b => b
 .Must(
 a => a.Term(z => z.Company.Code, param1),
 a => a.Terms(z => z.Company.Id, param2),
 a => a.Terms(z => z.Company.Field1.Id, param3)
  )))
 .Query(b => b.Bool(q => q.Should
  (n => n.Match(a => a.OnField(d => d.Company.Field2).Query(param5).Operator(Operator.And)),
   n => n.Match(a => a.OnField(d => d.Company.Field3).Query(param5).Operator(Operator.And)),
   n => n.Match(a => a.OnField(d => d.Company.Field4).Query(param5).Operator(Operator.And)),
   n => n.Match(a => a.OnField(d => d.Company.Field5).Query(param5).Operator(Operator.And))
  )))))
  .Size(10)
  .SortDescending(n => n.DtCreate));

How can I find out how many documents suitable request using Nest?

Answer 1

There is a Total property on ISearchResponse which holds the total number of documents that matched the query. In your example, that would be search.Total.

Answer 2

The best way is to use the method Count as proposed by the official documentation

here the code

var result = client.Count<ElasticsearchProject>();
