Hi, I am currently using Bing News API, using the base_url = "https://api.bing.microsoft.com/v7.0/news/search" headers = {"Ocp-Apim-Subscription-Key": api_key} I set the parameter as t = 0 # I will change t from 0 to 10 manually count = 50 offset = t * count params = { "q": "Microsoft", "count": count, "offset": offset, "since": "2022-10-09", "sortBy": "Relevance" # "Date". } Using these parameters, I want to fetch news from 2022-10-09 until now. There's some issues I figured out and wonder if you can help me with answer them: If I change the "sortBy" from "Relevance" to "Date", the number of news I can retrieved decreased hugely. If I use "Relevance", I can get 154 news information, however, if I use "Date", there are only 67. Why we have this difference? If I use "Date", I can only get news whose "datePublished" between 2023-10-06 and 2023-10-09 (today). However, if I use "Relevance", the "datePublished" time range is larger. I would really want to use the "sortBy: "Date" " parameter because it gives a better time series data. But why the time frame of this choice is so narrow? From your documentation, there's seems no way to specify a timeframe like, I want data between 2022-10-01 and 2022-12-31. Is it true? In your generated Json file, the totalEstimatedMatches of this parameter setting is 41200. However, even using the "Relevant" parameter, I could only get 154. It was not a common sense to me that we can only get 154 Apple news within a year. Especially when "datePublished" time range is as large as 2010 - 2023. I wonder if I need to change any settings or improve my parameter selection. Thanks for answering these questions. I am looking forward to your reply! With best regards, Rui

Bing news search API: timeframe of the news and the number of news we can get from the API

Hi,

I am currently using Bing News API, using the

base_url = "https://api.bing.microsoft.com/v7.0/news/search"
headers = {"Ocp-Apim-Subscription-Key": api_key}

I set the parameter as

t = 0  # I will change t from 0 to 10 manually
count = 50
offset = t * count

params = {
        "q": "Microsoft",
        "count": count,
        "offset": offset,
        "since": "2022-10-09",
        "sortBy": "Relevance" # "Date".
    }

Using these parameters, I want to fetch news from 2022-10-09 until now. There's some issues I figured out and wonder if you can help me with answer them:

If I change the "sortBy" from "Relevance" to "Date", the number of news I can retrieved decreased hugely. If I use "Relevance", I can get 154 news information, however, if I use "Date", there are only 67. Why we have this difference?

Thanks for answering these questions. I am looking forward to your reply!

Thanks for reaching out to us. Below are some references you may want to look.

For your question 1, the difference in the number of news articles retrieved when using "Relevance" versus "Date" as the sorting parameter could be due to the way the API ranks and filters the results. When using "Relevance", the API may be returning more results that are relevant to the query, regardless of the date. When using "Date", the API may be filtering out more results that are not within the specified date range, resulting in fewer results.

The time frame of the news articles retrieved when using "Date" as the sorting parameter is limited to the past few days or weeks, depending on the current date. This is because the API is designed to return the most recent news articles first when using "Date" as the sorting parameter. If you want to retrieve news articles from a specific date range, you may need to use a different API or data source.

The Bing News API does not provide a way to specify a specific date range for the news articles retrieved**.** However, you may use the "since" parameter to retrieve news articles that were published after a specific date.

I hope this helps.

Regards,

Yutong

Thank you Yutong for your kind reply.

And I am wondering if you can give me some hint on my question 4. There's a huge gap between the "totalEstimatedMatches" and the data I can retrieved from API, using count and offset.

@YutongTie-MSFT Does bing news api still not provide a way to specify a specific date range for the news articles retrieved? and I don't see the follow-up answer for "In your generated Json file, the totalEstimatedMatches of this parameter setting is 41200. However, even using the "Relevant" parameter, I could only get 154. It was not a common sense to me that we can only get 154 Apple news within a year. Especially when "datePublished" time range is as large as 2010 - 2023. I wonder if I need to change any settings or improve my parameter selection." could you please share this answer with me too?
