c# - 使用映射创建索引的问题

Question

我将弹性搜索版本 7.1.0 和 NEST 6.7.0 与 Elasticsearch.Net 6.7.0 一起使用。当我试图创建一个索引时，我遇到了一个错误。

这是我的代码，我在 NEST 和 Elasticsearch.Net 6.4.0 版上使用了相同的代码，并且运行良好

var result =   Client.CreateIndex(DefaultIndex, c => c
                .Settings(s => s
                    .NumberOfShards(numberOfShards)
                    .NumberOfReplicas(numberOfReplicas)
                    .BlocksReadOnly(false)
                )
                .Mappings(m => m
                    .Map<SearchDocument>(mm => mm
                        .AutoMap(3)
                    )
                )
            );

这是我得到的错误

Answer 1

NEST 和 Elasticsearch.Net 6.7.0 与 Elasticsearch 7.x 不兼容。请使用 NEST 和 Elasticsearch.Net 7.x，目前最新发布的是7.0.0-alpha2。
