Question

我正在开发一个asp.net应用程序，我有庞大的数据库。我想实现弹性搜索。这是我在代码中所做的：

var node = new Uri("http://localhost:9200/");
            var setting = new ConnectionSettings(node);
            setting.DefaultIndex("businessuser");
            client = new ElasticClient(setting);

 CanadaBusinessDBEntities db = new CanadaBusinessDBEntities();
            client.DeleteIndex("businessuser", null);
            var ListofBusiness = db.CanadaTables.ToList();
            foreach (var Business in ListofBusiness)
            {
                var resutl = client.Index(Business, null);
            }

此代码是在构造函数中编写的，它获取所有记录，然后使用弹性搜索对它们进行索引。索引需要很长时间。我想问一下这是否正确？我是弹性搜索的新手。请建议更好的方法来做到这一点。

感谢。

你必须使用ElasticsearchContext Class of Nest。

private readonly ElasticsearchContext _elasticsearchContext;
private const string ConnectionString = "http://localhost:9200";
private readonly IElasticsearchMappingResolver _elasticsearchMappingResolver;


_elasticsearchMappingResolver = new ElasticsearchMappingResolver();
_elasticsearchContext = new ElasticsearchContext(ConnectionString, new ElasticsearchSerializerConfiguration(_elasticsearchMappingResolver,true,true));

出于删除目的，您可以像下面那样使用

 public void DeleteSkill(int  Id)
        {
            _elasticsearchContext.DeleteDocument<Tag>(Id);
            _elasticsearchContext.SaveChanges();
        }
