我正在使用.NET的ElasticSearch和NEST C#库进行我的第一步.这是我的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Nest;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

        var setting = new ConnectionSettings(new Uri("http://localhost:9200/"));
        setting.SetDefaultIndex("Post");
        var client = new ElasticClient(setting);

        var post = new Post();
        post.id = 1;
        post.title = "the title";

        var t = client.Index(post);

        var results = client.Search<Post>(s => s.From(0)
            .Size(10)
            .Fields(f => f.id, f => f.title)
            .Query(q => q.Term(f => f.title, "title", Boost: 2.0))
            );

    }
}
public class Post
{
    public int id { get; set; }
    public string title { get; set; }
}

我期望从Post 1获得结果,因为其中包含“ title”关键字,但结果集为空.我做错了什么？

解决方法:

问题是正在使用术语查询.这将仅与索引的确切文本匹配.术语查询是useful for id type searching.

如果您要进行*文本搜索,请尝试使用匹配查询进行通用的*文本搜索. You can read more about it here on the official docs,并希望通过熟悉文档来发现如何构建有趣且功能强大的查询.

祝好运
