Question

我在查询像这样的索引时发现了多个样本：

results = indexClient.Documents.Search<Hotel>("budget", parameters);

但是，在使用方面时，我什么也找不到。您如何使用SearchServiceClient和方面？

在搜索服务浏览器中，它将类似于：

&facet=Group

结果：

{
    "@odata.context": "https://xxx-dev.search.windows.net/indexes('influencers')/$metadata#docs",
    "@search.facets": {
        "Group@odata.type": "#Collection(Microsoft.Azure.Search.V2017_11_11.QueryResultFacet)",
        "Group": [
            {
                "count": 426,
                "value": "Gaming"
            },
            {
                "count": 388,
                "value": "Action Sports"
            },
            {

                "value": "Music"
            },
            {
                "count": 378,
                "value": "Sport"
            }
        ]
    },
    "value": [
        {
            "@search.score": 1,
            "id": "fc4b1200-fb91-4fe0-a251-beb351ee2988",

我们可以调查Azure搜索demo source code以获得答案。以下是Azure搜索演示中的代码段。

SearchParameters sp = new SearchParameters()    
{    
    ...
    Select = new List<String>() {"id", "agency", "posting_type",...},
    ....
    // Add facets    
    Facets = new List<String>() { "business_title", "posting_type", "level", "salary_range_from,interval:50000" },

};
// Add filtering

string filter = null;
if (businessTitleFacet != "")
filter = "business_title eq '" + businessTitleFacet + "'";
if (postingTypeFacet != "")

  {
    if (filter != null)
    filter += " and ";
    filter += "posting_type eq '" + postingTypeFacet + "'";

  }
 ....
 sp.Filter = filter;
 _indexClient.Documents.Search(searchText, sp);

具有方面的SearchIndexClient
