Elasticsearch.NET 版本 7 - 如何创建索引 [英] Elasticsearch.NET version 7 - How to Create Index

问题描述

在 Elasticsearch.NET 6.x 中，可以使用 IElasticClient 方法创建索引:

In Elasticsearch.NET 6.x, it is possible create an index using IElasticClient method:

var response = elasticClient.Create(
                    "my-index-name",
                    index =>  index .Mappings(
                        ms => ms.Map<MyDocumentType>(
                            x => x.AutoMap()
                        )
                    )
                );

方法在 Elasticsearch.NET 版本 7 中被删除.

Method is removed in Elasticsearch.NET version 7.

推荐答案

在 Elasticsearch.NET 版本 7 中与索引操作相关的方法被移到 IndicesNamespace 中，所以 IndexExists 方法已移至:

In Elasticsearch.NET version 7 methods related to indices operations are moved into IndicesNamespace, so IndexExists method has been moved to:

var response = elasticClient.Indices.Create(IndexName,
                    index => index.Map<ElasticsearchDocument>(
                        x => x.AutoMap()
                    ));

另请注意，Map(...) 方法不再嵌套在 Mappings(...) 方法内部.原因是 Elasticsearch 服务器版本 7 支持不支持每个索引的多种类型(请参阅 删除映射类型)，因此每个索引一个 Map 方法就足够了.

Also note, that Map(...) method is no longer nested inside of Mappings(...) method. Reason is that Elasticsearch server version 7 supports does not support multiple types per index (see Removal of mapping types), so one Map method per index is sufficient.

同样，不同的方法已移至各自的命名空间:

Similarly, different methods have been moved to their own namespaces:

• 猫
• 集群
• 图表
• SQL
• 节点
• 等等...
