嵌套弹性搜索：如何在 SearchRequest 对象中定位多种类型？

Question

我想使用 SearchRequest 对象对几种类型进行请求

我的请求类似于下面的代码：

var searchQuery = new BoolQuery
 {
      Should = shouldContainers,
      Filter = filterContainers
 };

var searchRequest = new SearchRequest<dynamic>()
{
     //Don't know how to target type
     Type = EType.All,
     //or 
     Type = typeof(obj1) && typeof(obj2)  
     Query = searchQuery,
     Size = size
     From = fromNumber,
     MinScore = 1
};

var response = await client.SearchAsync<dynamic>(searchRequest);

你知道是否有可能做这样的事情以及如何做到这一点？

Answer 1

如果你没有在端点中指定索引/类型，它将搜索整个集群。

更新：

    //
    // Summary:
    //     /_search
    //
    // Parameters:
    //   document:
    //     describes an elasticsearch document of type T, allows implicit conversion from
    //     numeric and string ids
    public SearchRequest();

    //
    // Summary:
    //     /{index}/_search
    //
    // Parameters:
    //   index:
    //     Optional, accepts null
    public SearchRequest(Indices index);

    //
    // Summary:
    //     /{index}/{type}/_search
    //
    // Parameters:
    //   index:
    //     Optional, accepts null
    //
    //   type:
    //     Optional, accepts null
    public SearchRequest(Indices index, Types type);

    // The second one is what you are looking for, query on specific index regardless type, it does `POST /{index}/_search`

    var searchRequest = new SearchRequest(myIndex){...} 
    var result = client.Search<dynamic>(searchRequest);
