For the last year or so, I have used this URL to list a union of 3 tags:
Earlier this afternoon, this changed behaviour and now seems to ignore the last
or and displays questions tagged as 1)
inno-setup or 2)
winapi which drastically cuts down the results.
The search summary now shows:
[inno-setup] or [vb6] [winapi]
Is this an expected change and if so, is there another way to display a union of 3+ tags?
