+If you want to exclude specific types of content, such as images, from the response, you can exclude them with the hyphen (minus) prefix to the responseFilter value. Separate excluded types with a comma:

 Although Bing did not return video and news results in the previous response, it does not mean that video and news content does not exist. It simply means that the page didn't include them. However, if you [page](./paging-webpages.md) through more results, the subsequent pages would likely include them. Also, if you call the [Video Search API](../bing-video-search/search-the-web.md) and [News Search API](../bing-news-search/search-the-web.md) endpoints directly, the response would likely contain results. 
 
 You are discouraged from using `responseFilter` to get results from a single API. If you want content from a single Bing API, call that API directly. For example, to receive only images, send a request to the Image Search API endpoint, `https://api.cognitive.microsoft.com/bing/v7.0/images/search` or one of the other [Images](https://docs.microsoft.com/rest/api/cognitiveservices/bing-images-api-v7-reference#endpoints) endpoints. Calling the single API is important not only for performance reasons but because the content-specific APIs offer richer results. For example, you can use filters that are not available to the Web Search API to filter the results.
