How do you form a compound query using Bing Marketplace API?

I have an application that is using the new Bing API from the Azure Datamarketplace. I used to be able to query the Bing API using a simple syntax using OR AND, etc. That doesn't seem to work in the new API.

Old syntax:

"Jacksonville Jaguars" OR "NFL Jaguars" OR "Atlanta Falcons"

That would give me a query with any of those phrases (I am making a rt_Sports query for news).

I am calling HttpEncode on the query first, but am still not getting results. It works if I remove all the " marks, but then I am getting results sometimes for news about Falcons and Jaguars (the animals)... Not what I wanted.

Anyone have any idea how you can form a query that takes multiple phrases?

I have tried to not use the OR, not use the ', use a ", use the | instead of OR. All of these work against BING the website, just not in the API.

I just tried this via Bing and got 36 Million results:

Same thing in the API returns 0.

I got an email from a friend who I also emailed this question out to and his thought was that I was going about it wrong. That there should be a way to form a LINQ query off the Bing object with multiple where clauses.

But I don't see how that would be possible. You allow a BingSearchContainer and then call the News method on the container. The News method has only a single Query parameter.

var bingContainer = new Bing.BingSearchContainer(new Uri("https://api.datamarket.azure.com/Bing/Search"));

bingContainer.Credentials = new NetworkCredential(App.BingAPIAccountKey, App.BingAPIAccountKey);

string unifiedQuery = "NFL Football | Jacksonville Jaguars | Atlanta Falcons";

var newsQuery = bingContainer.News(unifiedQuery, null, "en-US", "Strict", null, null, null, "rt_Sports", "Relevance");

newsQuery.BeginExecute(BingNewsResultLoadedCallback, newsQuery);

Solution

Try changing unifiedQuery to the following:

var unifiedQuery = "'NFL Football' or 'Jacksonville Jaguars' or 'Atlanta Falcons'";

I tried something very similar to your sample code, using this format for the query string, and it worked for me:

var bingUri = new Uri("https://api.datamarket.azure.com/Bing/Search/v1/", UriKind.Absolute);
var bingContainer = new BingSearchContainer(bingUri);
bingContainer.Credentials = new NetworkCredential(BingAPIUserName, BingAPIAccountKey);
var unifiedQuery = "'NFL Football' or 'Jacksonville Jaguars' or 'Atlanta Falcons'";

var newsQuery = bingContainer.News(unifiedQuery, null, "en-US", "Strict", null, null, null, "rt_Sports", "Relevance");

var results = newsQuery.Execute();
foreach (var item in results)
{
    Console.WriteLine(item.Title);
}

Here are my results:

The format for the unifiedQuery string is basically the OData URI query string format. For a full description of how these query strings work, check out the OData URI conventions documentation at http://www.odata.org/documentation/uri-conventions.
