How to page through results from the Bing Search APIs

  • आलेख

Warning

On October 30, 2020, the Bing Search APIs moved from Azure AI services to Bing Search Services. This documentation is provided for reference only. For updated documentation, see the Bing search API documentation. For instructions on creating new Azure resources for Bing search, see Create a Bing Search resource through the Azure Marketplace.

When you send a call to the Bing Web, Custom, Image, News or Video Search APIs, Bing returns a subset of the total number of results that may be relevant to the query. To get the estimated total number of available results, access the answer object's totalEstimatedMatches field.

For example:

{
    "_type" : "SearchResponse",
    "webPages" : {
        "webSearchUrl" : "https:\/\/www.bing.com\/cr?IG=3A43CA...",
        "totalEstimatedMatches" : 262000,
        "value" : [...]
    }
}

Paging through search results

To page through the available results, use the count and offset query parameters when sending your request.

Note

  • Paging with the Bing Video, Image, and News APIs applies only to general video (/video/search), news (/news/search) and image (/image/search) searches. Paging through trending topics and categories is not supported.
  • The TotalEstimatedMatches field is an estimate of the total number of search results for the current query. When you set the count and offset parameters, this estimate may change.
Parameter Description
count Specifies the number of results to return in the response. Note that the default value of count, and the maximum number of results that you may request varies by API. You can find these values in the reference documentation under Next steps.
offset Specifies the number of results to skip. The offset is zero-based and should be less than (totalEstimatedMatches - count).

As an example, if you want to display 15 results per page, you would set count to 15 and offset to 0 to get the first page of results. For each subsequent API call, you would increment offset by 15. The following example requests 15 webpages beginning at offset 45.

GET https://api.cognitive.microsoft.com/bing/v7.0/search?q=sailing+dinghies&count=15&offset=45&mkt=en-us HTTP/1.1  
Ocp-Apim-Subscription-Key: 123456789ABCDE  
Host: api.cognitive.microsoft.com

If you use the default count value, you only need to specify the offset query parameter in your API calls.

GET https://api.cognitive.microsoft.com/bing/v7.0/search?q=sailing+dinghies&offset=45&mkt=en-us HTTP/1.1  
Ocp-Apim-Subscription-Key: 123456789ABCDE  
Host: api.cognitive.microsoft.com

When using the Bing Image and Video APIs, you can use the nextOffset value to avoid duplicate search results. Get the value from the Images or Videos response objects, and use it in your requests with the offset parameter.

Note

The Bing Web Search API returns search results that can include webpages, images, videos, and news. When you page through search results from the Bing Web Search API, you are paging only WebPages, and not other answer types such as images or news. Search results in WebPage objects may include results that appear in other answer types as well.

If you use the responseFilter query parameter without specifying any filter values, don't use the count and offset parameters.
