如何使用 Azure 认知搜索进行分面搜索?
How to do faceted search with Azure cognitive search?
我正在尝试在 Azure 认知搜索中进行分面搜索。我正在使用 postman(和 curl)进行测试。
获得了一个可显示的字段 state_name
。在 https://docs.microsoft.com/en-us/rest/api/searchservice/search-documents 之后,如果我将 POST 请求负载发送为:
{
"facets": "state_name"
}
它returns这个错误:
{
"error": {
"code": "",
"message": "The request is invalid. Details: parameters : When trying to read a null collection parameter value in JSON Light, a node of type 'PrimitiveValue' with the value 'state_name' was read from the JSON reader; however, a primitive 'null' value was expected.\r\n"
}
}
进行分面搜索的正确方法是什么?
更新:
payload中的facets
应该是一个数组:
{
"facets": ["state_name"]
}
如图https://docs.microsoft.com/en-us/rest/api/searchservice/search-documents#bkmk_examples
您需要将构面字段指定为 url 的一部分:
GET /indexes/hotels/docs?search=*&facet=state_name&api-version=2019-05-06
