The udm=web parameter has been doing the job for a while now. It's a shame you have to know about an undocumented flag to get the old behavior.
That flag is the result of clicking on the "Web" tab of the results page, so it kinda is a documented feature. All the tabs have their own udm value (e.g. image search is 2, AI mode is 50, etc.).
