在ElasticSearch中使用Bulk.IndexMany指定_id字段

您可以使用

_id

BulkDescriptor

public class Message{    public string Content { get; set; }}

例如，使用递增计数器设置ID

var documents = new[] {    new Message { Content = "message 1" },    new Message { Content = "another message" },    new Message { Content = "yet another one" }};var indexName = "index-name";   var id = 0;client.Bulk(bd => bd    .IndexMany(documents, (descriptor, s) => descriptor.Index(indexName).Id(++id)));

产生以下请求

POST http://localhost:9200/_bulk{"index":{"_index":"index-name","_type":"message","_id":1}}{"content":"message 1"}{"index":{"_index":"index-name","_type":"message","_id":2}}{"content":"another message"}{"index":{"_index":"index-name","_type":"message","_id":3}}{"content":"yet another one"}
