使用Nest Client在Elasticsearch中加载完成字段 [英] Using Nest Client to load completion fields in Elasticsearch

问题描述

我想使用Nest将完成建议字段填充到索引中。在阅读了关于实施完成字段的 ElasticSearch博文后，我看到您可以具有以下属性： / p>

• 输入数组


• 单输出


• weight


• 有效载荷

我假设将这些数据加载到索引中，我需要包括在我的搜索对象上包含以上字段的实体？

解决方案

我能够通过创建几个类来终止完成字段，并按照 FluentMappingFullExample 单元测试，具体如下：

  .Completion（s => s 
 .Name（p => p.Name.Suffix完成））
 .IndexAnalyzer（standard）
 .SearchAnalyzer（standard）
 .MaxInputLength（20）
 .Payloads（）
 .PreservePositionIncrements ）
 .PreserveSeparators（）
）
  

对于我的搜索类型实体，我创建一个名为建议的字段，并将其命名为CompletionField。

  public class CompletionField 
 { 
 public CompletionField（）
 {
 Input = new List< string>（）; 
} 
 
 public List< string>输入{get;组; } 
 // public string Output {get;组; } 
 public int Weight {get;组; } 
 public Payload Payload {get;组; 
} 
 
 public class Payload 
 {
 public int ID {get;组; } 
} 
  

在使用dapper从db上加载实体后，我然后循环结果，并加载我的完成字段与我想要的适当的输入。然后我可以成功调用建议API并查询这些数据。我希望这有助于别人。

I would like to use Nest to populate the completion suggestion field into an index. After reading this ElasticSearch blog post about implementing a completion field I see you can have the following properties:

• array of inputs
• single output
• weight
• payload

I am assuming that to load this data into an index I need to include an entity on my search object that contains the above fields?

解决方案

I was able to finally load the completion field by creating several classes, and following the FluentMappingFullExample unit test, specifically the following part:

                    .Completion(s=>s
                    .Name(p=>p.Name.Suffix("completion"))
                    .IndexAnalyzer("standard")
                    .SearchAnalyzer("standard")
                    .MaxInputLength(20)
                    .Payloads()
                    .PreservePositionIncrements()
                    .PreserveSeparators()
                )

For my search type entity, I created a field called suggest and made it of type CompletionField.

 public class CompletionField
{
    public CompletionField()
    {
        Input = new List<string>();
    }

    public List<string> Input { get; set; }
    //public string Output { get; set; }
    public int Weight { get; set; }
    public Payload Payload { get; set; }
}

public class Payload
{
    public int ID { get; set; }
}

After I loaded my entity from the db using dapper, I then looped over the results and loaded my completion field with the appropriate inputs that I wanted. I was then able to successfully call the suggest API and query on this data. I hope this helps someone else.
