Example of doing aggregated search using Elasticsearch and NEST

gistfile1.cs

var result = elasticClient.Search<ErrorDocument>(search => search
  .SearchType(SearchType.Count)
  .Query(q => q
    .Range(range => range
      .OnField(field => field.Time)
      .GreaterOrEquals(DateTime.UtcNow.AddHours(-24))
      .LowerOrEquals(DateTime.UtcNow)
    )
  )
  .Aggregations(a => a
    .DateHistogram("histogram", s => s
      .Field(field => field.Time)
      .Interval("hour")
      .MinimumDocumentCount(0)
    )
  )
);
 
var dateHistogram = result.Aggs.DateHistogram("histogram");
