Bing API Azure Marketplace: how to know whether there are more results?

I am using the Bing Search API in Windows Azure Marketplace (i.e., the API that replaces the old Bing 2.0 API, that expires on 1st August 2012). The Migration Guide provided by Microsoft states:

If there are no more pages of results, the /feed/link[@rel=’next’] property will no longer appear [...].

However, it seems that this is not always the case. For example, a News query for "Roger Federer" does not contain a link element:

Request: https://api.datamarket.azure.com/Data.ashx/Bing/Search/News?Query=%27"Roger+Federer"%27

Response:

<feed xmlns:base="https://api.datamarket.azure.com/Data.ashx/Bing/Search/News"
    xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices"
    xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"
    xmlns="http://www.w3.org/2005/Atom">
    <title type="text">"Roger Federer"</title>
    <subtitle type="text">Bing News Search</subtitle>
    <id>https://api.datamarket.azure.com/Data.ashx/Bing/Search/News?Query='"Roger Federer"'</id>
    <rights type="text"/>
    <updated>2012-07-26T15:43:03Z</updated>
    <entry>
        <!-- ... -->
    </entry>
    <!-- ... -->
</feed>

Nevertheless, there are more news: https://api.datamarket.azure.com/Data.ashx/Bing/Search/News?Query=%27"Roger+Federer"%27&$skip=50

Does anybody know where the problem might be? (Or where there is reliable documentation for the API?)

I cannot reproduce this anymore: the response now contains a link element.

I suppose the Bing guys have fixed the problem in the meantime.

One thing to do is to update your BingSearchContainer.cs - I found there was an older version when I first started using it that caused me all sorts of problems like this. When I updated a lot of things started working.

I think the problem is that the BingSearchContainer is "fixing" your query and messing you up. Try the following:

Then try to do the query without the " marks. It will probably succeed and return results.

Try to use ' instead, you will probably get some results.

I think the container is escaping all your queries as a single phrase match by default. So just adding a search will work. Now when you really do have two phrases you need to search for... That I can't get working yet either.
