Here is a link that domonstrates this behavior:


Note that:

  • react is an alias for reactjs
  • I included any as the search mode.

My browser shows that it redirects to:


It throws away the ?mode=any part, and it gets autofilled with all.

I allow users of an app to select tags and generate a link, so it is not really super easy to limit to non-alias tags.

The any and all modes are part of the question search fields when you are searching by tags:

  • This simply isn't a bug. Current functionality strips all query strings from a URL on a redirect, because we would have already updated user preferences based on all the valid ones that were in the URL before the redirect. You're welcome to request we not do this, but just saying that's unlikely to happen. – animuson May 9 '17 at 17:03
  • What is mode=any? – Cai May 9 '17 at 17:03
  • @Cai I assumed it's something that gets appended to the URL which helps whatever app adds it to continue functioning correctly. It's nothing we support on our sites. – animuson May 9 '17 at 17:05
  • I'm not sure I follow. The original url asks explicitly for mode=any. This is a valid option. After the redirect, I am given a view with mode=all, and no results. What user preferences are possibly involved there? – captncraig May 9 '17 at 17:05
  • mode=any says "show me questions with any of these tags". It is a valid param, generated by your own page. It is not something specific to my app. – captncraig May 9 '17 at 17:06
  • @OliviaRuth Which page adds this to the URL? I've never seen it before in all the years I've been here. If it's not working properly, it's probably because it's a forgotten feature that no one realizes even works. – animuson May 9 '17 at 17:08
  • @Olivia where/when/how is it generated by a Stack Exchange search? I've never seen it before – Cai May 9 '17 at 17:09
  • Its part of the new nav / custom search thing. Its really nice to have. See edit. – captncraig May 9 '17 at 17:11

    Oh this is another one of those new nav things. That entire system is... pretty broken right now. It's fate is not entirely clear. Still being discussed whether someone will be assigned to finish it or if it will just be dropped altogether. You won't see anything further happen with that until our new Product Manager gets up to speed on the project. – animuson May 9 '17 at 17:14

    That's kinda crappy. Is there an equivalent feature in the old nav for showing questions marked with any of a set of tags? – captncraig May 9 '17 at 17:33
  • @OliviaRuth The easiest thing is to mark them as favorite tags and use search for intags:mine. But you can also use OR operator between tags: meta.stackexchange.com/questions/tagged/discussion+or+bug – user315433 May 9 '17 at 17:53
  • @Gerry that seems to work tolerably well across old and new nav. Thanks! – captncraig May 9 '17 at 18:35

    @animuson: the entire system has been working really really well for me, I wasn't aware of any breakage and I'd hate for it to see it die. – Martijn Pieters May 23 '17 at 6:38
  • @MartijnPieters - Me too, except for the whole forgetting that I selected 50 posts per page thing. That is rather annoying, but that aside, I have been enjoying the customization available. – Travis J May 24 '17 at 18:59
