Indeed, there are mechanisms that can make cross-wiki searching more feasible. In fact, one mechanism we are in the very early stages of exploring is merging all the projects in a given language into a single index, so that one could search all projects in a language, rather than just a single project in a given language. I have no timeline here; as I said, we're in the very early stages, and of course we have other work on the go at the same time.

 

I plan to worry more about the user experience implications that I mentioned once we're a bit closer to solving the technical feasibility questions. As you've shown, these are definitely solvable problems, but I don't want to put the cart before the horse, as it were. :-)

Thanks,
