AggregationContainer 与 AggregationDescriptor

Question

我正在尝试将范围数组发送到聚合描述符，但 Lambda 表达式需要逗号分隔的表达式

.Aggregations(agg => { AggregationDescriptor ag = agg.Terms("objectTypes", ot => ot.Field("doc.objectType"));

            if (!parameters.ContainsKey("userID"))
                ag = ag.Terms("users", ot => ot.Field("doc.entryUserID"));//.Field("doc.sourceUserID")))
            ag.Terms("commentTypes", ot => ot.Field("doc.commentType"));

            if (!parameters.ContainsKey("dateRange"))
            {
                Dictionary<string, SearchDateRange> dateMap = GetDateRangeMap();

                ag.DateRange("dates", dr => dr.Field("doc.date").Format("yyyy-MM-dd")
                    .Ranges(r1 => r1.Key("Today").From(dateMap["Today"].startDate.Value.ToString("yyyy-MM-dd")).To("now"),
                            r2 => r2.Key("SinceWednesday").From(dateMap["Today"].startDate.Value.ToString("yyyy-MM-dd")).To("now"),
                            r3 => r3.Key("ThisYear").From(dateMap["ThisYear"].startDate.Value.ToString("yyyy-MM-dd")).To("now"),
                            r3 => r3.Key("Last2Years").From(dateMap["Last2Years"].startDate.Value.ToString("yyyy-MM-dd")).To("now"),
                            r4 => r4.Key("Last3Years").From(dateMap["Last3Years"].startDate.Value.ToString("yyyy-MM-dd")).To("now")
                            ));

            }

以上代码有效。

下面我想使用 Range[] 数组并将其传递给聚合描述符，但我不能，但我可以使用范围数组创建一个 AggregationContainer。如何将这两部分结合在一起？

            if (!parameters.ContainsKey("revenueRange") && docTypes.Contains(CouchbaseDocumentType.Company))
            {
                Dictionary<string, SearchNumberRange> numMap = GetMoneyRangeMap();
                Range<double>[] ranges = numMap.Select(m =>
                {
                    var r = new Range<double>().Key(m.Key);
                    if (m.Value.low.HasValue) r.From(m.Value.low.Value);
                    if (m.Value.high.HasValue) r.To(m.Value.high.Value);
                    return r;
                }).ToArray();

                AggregationContainer agr = new AggregationContainer
                {
                    Range = new RangeAggregator { Field = "doc.lastFinancial.revenueUSD", Ranges = ranges }
                };

            }

            return ag;
        }
        )

我创建了一个简单的示例来向您展示如何实现这一点。

var funcs = new List<Func<Range<double>, Range<double>>>();

funcs.Add(range => new Range<double>().From(1).To(2));
funcs.Add(range => new Range<double>().From(3).To(4));

var searchResponse = client.Search<Document>(
    s => s.Aggregations(agg => agg.Range("range", descriptor => descriptor.Field(f => f.Number).Ranges(funcs.ToArray()))));

文件class:

public class Document
{
    public int Id { get; set; }
    public double Number { get; set; }
}

希望您将它放入您的上下文中不会有问题。
