c# – ElasticSearch.NET NEST搜索网址

概述我正确的索引路径是POST：/ foo / _search但是下面的代码命中POST：/ foo / bar / _search. var node = new Uri("http://elasticsearch-server.com:9200");var settings = new ConnectionSettings(node);settings.DefaultIndex("foo"); 我正确的索引路径是POST：/ foo / _search但是下面的代码命中POST：/ foo / bar / _search.

var node = new Uri("http://elasticsearch-server.com:9200");var settings = new ConnectionSettings(node);settings.DefaultIndex("foo");var clIEnt = new ElasticclIEnt(settings);var response = clIEnt.Search<bar>(s => s.query(q => q.Term(o => o.username,"test")));// POCO for response fIEldspublic class bar{    public int userID { get; set; }    public string username { get; set; }    public DateTime createdTime { get; set; }}

上面的代码响应返回以下消息;

ValID nesT response built from a successful low level call on POST: /foo/bar/_search

如何正确设置搜索路径？

试验1

当我省略settings.DefaultIndex(“foo”);如下所示,它会抛出ArgumentException,但是当我设置DefaultIndex()时,Search< T>使用T名称作为第二个路径.

ArgumentException: Index name is null for the given type and no default index is set. Map an index name using ConnectionSettings.MapDefaultTypeIndices() or set a default index using ConnectionSettings.DefaultIndex().

试用2
参考documentation,

var settings = new ConnectionSettings(node).MapDefaultTypeIndices(m => m.Add(typeof(bar),"foo"));

以上代码在响应中返回相同的结果.

ValID nesT response built from a successful low level call on POST: /foo/bar/_search

解决方法 通过nesT公开的大部分Elasticsearch API都是强类型的,包括.Search< T>();使用此端点,“index”和“type”都将从T推断,但有时您可能希望将不同的值设置为推断的值.在这些情况下,您可以在搜索流畅的API(或搜索对象,如果使用对象初始化程序语法)上调用其他方法来覆盖推断的值

voID Main(){    var pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));    var connectionSettings = new ConnectionSettings(pool)            .DefaultIndex("foo");    var clIEnt = new ElasticclIEnt(connectionSettings);    // POST http://localhost:9200/foo/bar/_search    // Will try to deserialize all _source to instances of bar    clIEnt.Search<bar>(s => s        .MatchAll()    );    // POST http://localhost:9200/foo/_search    // Will try to deserialize all _source to instances of bar    clIEnt.Search<bar>(s => s        .AllTypes()        .MatchAll()    );    // POST http://localhost:9200/_search    // Will try to deserialize all _source to instances of bar    clIEnt.Search<bar>(s => s        .AllTypes()        .Allindices()        .MatchAll()    );    connectionSettings = new ConnectionSettings(pool)            .InferMapPingFor<bar>(m => m                .Indexname("bars")                .Typename("barbar")            );    clIEnt = new ElasticclIEnt(connectionSettings);    // POST http://localhost:9200/bars/barbar/_search    // Will try to deserialize all _source to instances of bar    clIEnt.Search<bar>(s => s        .MatchAll()    );    // POST http://localhost:9200/bars/_search    // Will try to deserialize all _source to instances of bar    clIEnt.Search<bar>(s => s        .AllTypes()        .MatchAll()    );    // POST http://localhost:9200/_all/barbar/_search    // Will try to deserialize all _source to instances of bar    clIEnt.Search<bar>(s => s        .Allindices()        .MatchAll()    );    // POST http://localhost:9200/_search    // Will try to deserialize all _source to instances of bar    clIEnt.Search<bar>(s => s        .Allindices()        .AllTypes()        .MatchAll()    );}public class bar{    public int userID { get; set; }    public string username { get; set; }    public DateTime createdTime { get; set; }}
