使用 C# Nest 在 ElasticSearch 中按短语聚合

Question

这是我的汇总：

return a =>
                    a.Terms("Group1", t => t.Field(ff => ff.ItemAttributeDesc1).
                        Aggregations(aa => aa.Terms("Value1", tt => tt.Field(fff => fff.SearchedFilterValue1))))
                    .Terms("Group2", t => t.Field(ff => ff.ItemAttributeDesc2).
                        Aggregations(aa => aa.Terms("Value2", tt => tt.Field(fff => fff.SearchedFilterValue2))))
                    .Terms("Group3", t => t.Field(ff => ff.ItemAttributeDesc3).
                        Aggregations(aa => aa.Terms("Value3", tt => tt.Field(fff => fff.SearchedFilterValue3))))
                    .Terms("Group4", t => t.Field(ff => ff.ItemAttributeDesc4).
                        Aggregations(aa => aa.Terms("Value4", tt => tt.Field(fff => fff.SearchedFilterValue4))))
                    .Terms("Group5", t => t.Field(ff => ff.ItemAttributeDesc5).
                        Aggregations(aa => aa.Terms("Value5", tt => tt.Field(fff => fff.SearchedFilterValue5))))
                    .Terms("Group6", t => t.Field(ff => ff.ItemAttributeDesc6).
                        Aggregations(aa => aa.Terms("Value6", tt => tt.Field(fff => fff.SearchedFilterValue6))))
                    .Terms("Group7", t => t.Field(ff => ff.ItemAttributeDesc7).
                        Aggregations(aa => aa.Terms("Value7", tt => tt.Field(fff => fff.SearchedFilterValue7))))
                    .Terms("Group8", t => t.Field(ff => ff.ItemAttributeDesc8).
                        Aggregations(aa => aa.Terms("Value8", tt => tt.Field(fff => fff.SearchedFilterValue8))))
                    .Terms("Brands", t => t.Field(ff => ff.VendorSearch).Size(60).Order(TermsOrder.TermAscending))
                    .Terms("Category", t => t.Field(ff => ff.MainSearch))
                    .Range("Price", ra => ra.Field(ff => ff.SalePrice)
                        .Ranges(
                        pr => pr.From(50).To(100),
                        pr => pr.From(100).To(250),
                        pr => pr.From(250).To(500),
                        pr => pr.From(500).To(750),
                        pr => pr.From(750).To(1000),
                        pr => pr.From(1000).To(1500),
                        pr => pr.From(1500).To(2000),
                        pr => pr.From(2000).To(2500),
                        pr => pr.From(2500).To(3000),
                        pr => pr.From(3000).To(3500),
                        pr => pr.From(3500)));

除一件事外，一切正常。我必须按完全匹配进行汇总。例如，如果我有术语字段 "Field"（一个词），它工作正常。但是，如果该术语包含多个单词（或具有特定符号），则它不起作用。不起作用，因为用空格和符号弹性拆分短语。我需要 100% 匹配这里。谁能帮我解决这个问题？

发生这种情况是因为您正在聚合的字段被映射为分析字符串，这是字符串类型的默认映射，要解决此问题，请将您正在聚合的相关字段映射为 type: string 和 index: not_analyzed
