Android Search Market on Keyword URL?

To Launch the market I usually do this:

Intent intent = new Intent( Intent.ACTION_VIEW, Uri.parse("market://search?q=pname:com.package.package2.package3")); startActivity(intent);

But I would like to run a search based o开发者_C百科n a keyword like "Happy Toasters"

What is the URL for that kind of search?

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://search?q=your keewords here"));
startActivity(intent);
