gistfile1.cs

var result = elasticClient.Search<ErrorDocument>(s => s
    .FacetDateHistogram(fd => fd
        .OnField(p => p.Time)
        .Interval(DateInterval.Day)
        .Global()
        .FacetFilter(ff => ff
            .Range(rf => rf
                .From(DateTime.UtcNow.AddDays(-14))
                .To(DateTime.UtcNow)
            )
        )
    )
);
var facetBucket = result.Facet<DateHistogramFacet>(p => p.Time);
