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) vb AND winapi which drastically cuts down the results.

The search summary now shows:

questions tagged

[inno-setup] or [vb6] [winapi]

Is this an expected change and if so, is there another way to display a union of 3+ tags?

    I can confirm this strange behavior. I'm noticing the same thing and it just started today for me.

  • @hims056: Not certain that's related; that's a query with only one or and a wildcard tag. Sep 13, 2012 at 14:57
  • Yup, I can confirm it as well. It's independent of the tags used, and only the first or is honoured. Using the search box to construct the tag search doesn't help. Sep 13, 2012 at 15:21

    Also fails with the alternative tagnames= format. See this answer for an example of a 17-tag-union that no longer works.

My apologies; this change yesterday was a little bit over zealous. I've dialed it back a few notches, and it should be approaching sanity in a few minutes.

  • Woo, "18,130 questions tagged", thanks :)
