# Should we retroactively tag all relevant questions that are missing a relevant tag, or not?

For example, I've just now realized that,

When searching questions that contain the word "palindrome" but do not contain the appropriate tag [palindrome], i.e. palindrome -[palindrome] , we get that there are over $$600$$ results.

I went on to tag around 30 such questions (increasing the total number of tagged questions from 70 to 100), but then I stopped mainly for two reasons. First, all of those questions will get bumped up to the front page and prevent new questions from showing in the period while the tags are being edited. Secondly, 600 questions is not a small number and will take some time.

I must admit that this is my fault because a few years ago, I was passionate about the properties of palindromes and was the one to create the tag (by simply adding it to new questions I was posting), but, I did not consider that a lot of old questions that have been asked in the past and are related to this topic, will now be missing out on this tag.

Should we, and how, tag these questions?

Is it possible for someone (a moderator or admin?) to retroactively add the tag to all these questions?

Or should every such question be reviewed individually and tagged appropriately? (Is it okay for me to continue tagging every question individually?)

Should we NOT tag these questions?

Or is there a third option that should take action?

I.e. not all questions that involve prime numbers have the tag [prime-numbers]. Therefore, should all these questions that are missing the tag [palindrome] just be left alone?

• It seems you did not search for questions though, you'd need to add is:q doing that one arrives at around 250. – quid Aug 30 '20 at 21:28
• @quid Thank you for that. Actually my main concern was, If would go and edit all those questions, would that be okay or would that amount to something like "spamming the front page with edits bumps of old questions"? – Vepir Aug 30 '20 at 21:32
• The one thing you absolutely shouldn't do, Vepir, is bump lots of old questions up to the front page in a short time span. Three or four old questions bumped per day is about right. I recognize that at that rate it will take roughly forever to get the appropriate tag on all those old questions, and it would be much better if the system could be induced to make all the changes at once without bumping anything, but if that's not an option then I urge you to limit yourself to three or four a day. – Gerry Myerson Aug 30 '20 at 22:18
• @GerryMyerson Thank you, that was the reason why I stopped and decided to ask here before doing anything more. – Vepir Aug 30 '20 at 22:22
• @GerryMyerson I think that comment makes a fine answer, if you will post it as such! Thanks. – amWhy Aug 31 '20 at 1:17
• @amWhy, no can do – technical reasons – long story. But you have my blessing if you want to post my comment as an answer. – Gerry Myerson Aug 31 '20 at 1:53
• Thanks, @GerryMyerson, for the fine answer! – amWhy Aug 31 '20 at 2:16
• Searching palindrome -[palindrome] -[formal-languages] is:q closed:no for relevant questions. – Vepir Sep 1 '20 at 9:48
