@Zacky The same user requested reopening of one of those questions 2 days ago on meta, hence the ambiguity regarding undelete vs reopen seems irrelevant. In any event, lacking some comment from @Batominovski to the contrary, I am forced to assume that they want the question reopened because they answered it. Not disclosing one's affiliation with a post on which one wants action to be taken seems underhanded.

@XanderHenderson Well, the meta link changes the situation indeed. Also the lack of the response doesn't force you to assume that, but it's your choice. In any event they updated the post from meta that you linked to and if they don't want to answer to you specifically (here) I think that's a decent approach to handle the situation (by editing).

I didn't response, because I have no interest in heated debate. I am only interested in the values of the questions I asked to be undeleted.

May I ask how people on GENTLE find deleted posts? I could only see mine, and therefore, it is not possible for me to ask to undelete other questions I may be interested in.

Anyway, I would like to request that this question be undeleted again: UQ1. I think there is sufficient context now. And yes, I answered the question.

Regarding finding deleted posts, I could also obviously find ones that I bookmarked. Is it possible to find others?

@Batominovski As you're 10k+, you can search among your own deleted posts. For posts by other, you can try to use SEDE, but the possibilities what you can use to search are rather limited.

I think details are explained in some posts on meta, let me try to find a link.

@Batominovski I can only answer for myself. Lately I've used queries, see this meta post, typically by making small modification to them, or simply as you see those. Another way to find them is to go directly into this room, but everything can already be found using the above queries.

And this question has also been added some more context: UQ2. Is it possible to reopen it? Yes, I answered it.

I think that answers here give a reasonable overviews: Is there any way to see my deleted questions or answers?

I see the Zacky linked also to my answer here: Are there some tools to follow deletions on this site? The post shows several examples of SEDE queries. (And also links to the other post.)

Thank you for the information.

@Batominovski Could you clarify whether you're interested in looking for a specific post which you remember but it was deleted, or whether you want to find something like all recently deleted posts (perhaps with some additional criteria on those posts).

If you're interested in seeing the recent deletions, the lists available in the moderator tools might be also useful.

In the past, there are some situations where a question was deleted by the author, and I find the question interesting. Then, I failed to bookmark the question, and can't find it anymore.

In such situations, SEDE might help, although it might be difficult. If you remember some information about a post, you can find it from SEDE. (But you should keep in mind that the data in SEDE are updated only once a week.)

If you remember some information about the question, you can make a query which shows you candidates. For example, if you remember when the question was posted, you can use SEDE to list all deleted questions from that day. Still, then you will have to go through the list and click on all links one by one.

Thank you. I will try to learn how to use SEDE.

You can see here an example what it would look like: data.stackexchange.com/math/query/1175002/…

Here is a similar query restricted to one tag: data.stackexchange.com/math/query/845253/…

@Batominovski I have posted several queries in the answer which was already mentioned: Are there some tools to follow deletions on this site? I think they should be sufficient for many purposes - and to use them you don't need to know much about SEDE and SQL, it is enough that you change the parameters.

For example, in the query I linked above you can change the parameters directly in teh url - notice the part `Tagname=general-topology&Date1=2020-04-01&Date2=2020-04-02. Or in the input box which is under the query and above the result.

Anyway good luck with your experiments. If you have some trouble with the queries I made, you can simply ask me. (Maybe you can do so in my room - so that we do not digress here that much from the topic of this room.) I'll try to respond, if I have time.

Lovely! Thank you very much @MartinSleziak. Your examples are great and very helpful.

Oh, I didn't realize you have your room. I will ask my questions there if I have any.

See you later!
