Question

我想喝一杯啤酒并在Bing上搜索，以便从http://ratebeer.com返回结果。我得到的结果大多是好的，但有些结果（我认为）错了。

我遇到问题的啤酒之一被命名为“Kolk Maak Amber Ale”。

使用R和httr包，我的代码是：

url <- https://api.cognitive.microsoft.com/bing/v5.0/search?q=Kolk+Maak+Amber+Ale+site:http://ratebeer.com/beer&mkt=en-us
res <- GET(url,
          add_headers("Ocp-Apim-Subscription-Key"=APIkey))

其中“APIkey”是Microsoft-Cognitive-Services的个人密钥。结果是：

正如您在此处所见，列出的三种啤酒中没有一种显示正在搜索的啤酒（Kolk Maak Amber Ale）。但是，如果我按照

中的搜索响应链接

content(res)$webPages$webSearchUrl
[1] "https://www.bing.com/cr?IG=8E30DC638C5B48E592061644988A6924&CID=08A1C0B86E4C6A7527FCCADF6FAB6BD5&rd=1&h=28PvtjGreQkOBLSaPy_GCtmkd-G642-BVoJp814ve_8&v=1&r=https%3a%2f%2fwww.bing.com%2fsearch%3fq%3dKolk%2bMaak%2bAmber%2bAle%2bsite%253ahttp%253a%252f%252fratebeer.com%252fbeer&p=DevEx,5148.1"

使用浏览器（Chrome / Firefox / IE）我得到了正确的啤酒作为第一个结果。

为什么会这样？为什么所有搜索值都返回错误的网址，但使用物理浏览器返回正确的网址？我已经测试过的其他啤酒返回了正确的网址。

Answer 1

这非常有趣。如果您在搜索框中输入此内容，并使用加号，您可以从Bing获得正确的结果。没有他们，你就没有得到正确的页面：

科尔克+ Maak +琥珀+啤酒+站点：ratebeer.com

此外，此版本提供了正确的结果：网站：ratebeer.com Kolk Maak ale amber

但是这个版本不起作用：网站：ratebeer.com Kolk Maak琥珀啤酒

Microsoft Cognitive Bing Search API（v5）返回不正确的结果
