I do not use screenscraping.  I use the c# WebBrowser class and I get the HTML after I use this class to navagate to a URL.  I was able to use yandex by using a "&p=" to navagate to a particular page.

The duckduckgo search engine does not work this way, though.

I have found out how to make a specialized query for YANDEX in a modified URL.  I will ask DUCKDUCKGO for advice.

https://duckduckgo.com/api.html does not provide a solution.

Running this, http://api.duckduckgo.com/?q=stuff+to+search&format=xml , in a browser's address bar does not provide anything as http://duckduckgo.com/?q=stuff+to+search does.

This shouldn't be rocket science.  I am able to see the HTML code.  Shouldn't there be some sort of AJAX tag in the HTML that I can find to make use of?
