Bing Search API-当offset = 0时，突出显示不起作用

Question

当offset = 0时，我得到了这些信息：

{
        "id": "https:\/\/api.cognitive.microsoft.com\/api\/v7\/#WebPages.1",
        "name": ""Hello, World!" program - Wikipedia",
        "url": "https:\/\/en.wikipedia.org\/wiki\/Hello_world_program",
        ...
      }

当offset = 1（> 0）时，我得到了这些（这是我所需要的）

      {
        "id": "https:\/\/api.cognitive.microsoft.com\/api\/v7\/#WebPages.0",
        "name": "&quot;<b>Hello, World</b>!&quot; program - Wikipedia",
        "url": "https:\/\/en.wikipedia.org\/wiki\/Hello_world_program",
        ...
      }

PS：Bing Search API v5.0和v7.0遇到相同的问题。
