This link I use to see questions of interest to me has suddenly stopped working. Is this intentional?
Yes, we have refactored some of the search code; it shouldn't have killed anything, though. The breaking part of that query is the %2a ("sql-server*") - I'm investigating now.
As an update - indeed, the expansion of "foo*" to "fooA or fooB or fooC" has a small pre-existing sneeze, that was exposed by the revised code.
An an update to the update - this is fixed for the next deploy.
