这是你怎么做
private static void Main()
{
var defaultIndex = "my_index";
var pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));
var settings = new ConnectionSettings(pool)
.DefaultIndex(defaultIndex);
var client = new ElasticClient(settings);
if (client.IndexExists(defaultIndex).Exists)
client.DeleteIndex(defaultIndex);
var createIndexResponse = client.CreateIndex(defaultIndex, c => c
.Settings(s => s
.NumberOfShards(1)
.NumberOfReplicas(0)
)
.Mappings(m => m
.Map<Person>(mm => mm
.AutoMap()
.Properties(p => p
.Object<Address>(o => o
.Name(n => n.Address)
.AutoMap()
.Properties(pp => pp
.Text(t => t
.Name(nn => nn.Street)
.CopyTo(co => co
.Field(Infer.Field<Person>(ff => ff.Search))
)
)
)
)
)
)
)
);
var indexResponse = client.Index(new Person
{
LastName = "foo",
Address = new Address
{
Street = "bar"
}
} , i => i
.Refresh(Refresh.WaitFor)
);
var searchResponse = client.Search<Person>(s => s
.Query(q => q
.Match(m => m
.Field(f => f.Search)
.Query("bar")
)
)
);
}
public class Person
{
public string Search { get; set; }
public string LastName { get; set; }
public Address Address { get; set; }
}
public class Address
{
public string Street { get; set; }
}
本质上
搜索返回期望的文档

Elasticsearch中的字段不一定需要在C#POCO上作为属性公开,因为_source
不会包含它们的值。但是,作为属性公开对于强类型字段访问可能很有用。
