Copy_To与Nest的属性/ Fluent映射相结合
Copy_To与Nest的属性/ Fluent映射相结合
提问于 2015-11-22 04:23:02
我想在Nest中使用copy_to功能。我读到需要使用fluent映射(Elasticsearch Nest and CopyTo)。
是否可以使用基于属性的映射，然后在此基础上使用fluent映射来添加copy_to？若然，是否有例子？我很难找到答案。
要复制到的字段在我的模型类中不存在。我只想在elasticsearch里搜索。
[ElasticType(IdProperty = "CustomerId", Name = "customer_search")]
public class CustomerSearchResult : BindableBase
{
[ElasticProperty(Name = "customer_id", Index = FieldIndexOption.NotAnalyzed, Type = FieldType.String)]
public int CustomerId { get; set; }
[ElasticProperty(Name = "account_type", Index = FieldIndexOption.NotAnalyzed, Type = FieldType.String)]
public string AccountType { get; set; }
[ElasticProperty(Name = "short_name", Index = FieldIndexOption.NotAnalyzed, Type = FieldType.String)]
public string ShortName { get; set; }
[ElasticProperty(Name = "legacy_name", Index = FieldIndexOption.NotAnalyzed, Type = FieldType.String)]
public string LegacyName { get; set; }
[ElasticProperty(Name = "legacy_contact_name", Index = FieldIndexOption.NotAnalyzed, Type = FieldType.String)]
public string LegacyContactName { get; set; }
[ElasticProperty(Name = "city", Index = FieldIndexOption.NotAnalyzed, Type = FieldType.String)]
public string City { get; set; }
[ElasticProperty(Name = "state_abbreviation", Index = FieldIndexOption.NotAnalyzed, Type = FieldType.String)]
public string StateAbbreviation { get; set; }
[ElasticProperty(Name = "country", Index = FieldIndexOption.NotAnalyzed, Type = FieldType.String)]
public string Country { get; set; }
[ElasticProperty(Name = "postal_code", Index = FieldIndexOption.NotAnalyzed, Type = FieldType.String)]
public string PostalCode { get; set; }
}在上面的类中，我希望使用ShortName、LegacyName、LegacyContactName和copy_to --一个名为“搜索”的字段，它将是一个分析字段。

像下面这样的东西应该可以做到
void Main()
{
var settings = new ConnectionSettings(new Uri("http://localhost:9200"));
var connection = new InMemoryConnection(settings);
var client = new ElasticClient(connection: connection);
var indexResponse = client.CreateIndex("customer_searches", c => c
.AddMapping<CustomerSearchResult>(m => m
.MapFromAttributes()
.Properties(p => p
.String(s => s.Name("short_name").CopyTo("search").Index(FieldIndexOption.NotAnalyzed))
.String(s => s.Name("legacy_name").CopyTo("search").Index(FieldIndexOption.NotAnalyzed))
.String(s => s.Name("legacy_contact_name").CopyTo("search").Index(FieldIndexOption.NotAnalyzed))
.String(s => s.Name("search").Index(FieldIndexOption.Analyzed))
)
)
);
Console.WriteLine(Encoding.UTF8.GetString(indexResponse.RequestInformation.Request));
}哪种输出
{
"settings": {
"index": {}
},
"mappings": {
"customer_search": {
"properties": {
"customer_id": {
"index": "not_analyzed",
"type": "string"
},
"account_type": {
"index": "not_analyzed",
"type": "string"
},
"short_name": {
"index": "not_analyzed",
"copy_to": [
"search"
],
"type": "string"
},
"legacy_name": {
"index": "not_analyzed",
"copy_to": [
"search"
],
"type": "string"
},
"legacy_contact_name": {
"index": "not_analyzed",
"copy_to": [
"search"
],
"type": "string"
},
"city": {
"index": "not_analyzed",
"type": "string"
},
"state_abbreviation": {
"index": "not_analyzed",
"type": "string"
},
"country": {
"index": "not_analyzed",
"type": "string"
},
"postal_code": {
"index": "not_analyzed",
"type": "string"
},
"search": {
"index": "analyzed",
"type": "string"
}
}
}
}
}对Properties()的调用覆盖默认约定和属性映射，因此您需要指定字段也是not_analyzed。
