Most surprising to find that in 2026 ProtonMail still isn't making it trivial to search the current folder by default.

Subfolders are also excluded from search, but since you can't select multiple folders for search there's no way to manually replicate this feature either! As others have stated, allowing syntax like "in:foldername1 in:folderername2" would be helpful if devs didn't want to change the existing button-based UI.

When I am looking at emails in a specific folder by having clicked on that folder in the folder menu, why is that folder not listed as one of the defaults for search? I understand I can search directly in a folder without going to it first, but my usual path is going to a folder first to retrieve an email, realising that I need search to find it, then having to browse to that folder again in search. It's a monor irration but it grates each and every time

This now exists, but I would love a chip for "Trash" in the quick selector for "Search In". I search my Trash a lot (second only to everywhere). As it is now, it's a click, scroll, click because Trash isn't even on the first page of results in the Other menu.

It's good that you can search for mails in specific folders, but to my knowledge you can only select one to search in. In multiple occasions I was in need of it being able to search in multiple folders at once or in every folder except a specified one.

As others have written: If I'm already in a certain folder and hit "search", said folder (and *only* this folder) should be selected by default. After all, there's most probably a reason why I'm there.

It is nowadays possible to search in 'Spam' but not in 'Trash'. I would like to search in trash as well! To clean up my mail and permanently delete some mails. Have done this kind of organisation for many years and this is the first brand where I am unable to do so.
The app isn't always helpful since by accident sometimes mails land in my 'deleted' box through a wrong swipe. Which is not helping with this problem of being unable to search in your deleted box as an option.

Labels should be distinct from folders/inbox/archive so it can be combined.
eg., "label:bank in:archive is:starred"

Right now, you can search a label, but you can only do so if you use the label in place of those other two, not combined. If you're going to compete with gmail, having excellent (let alone passable) search is critical.

This is available at least in desktop website version. Click search field, then 'other' under "search in" in the dropdown. It lets you pick what folders & filters to search in.

The search term must be highlighted (e.g. yellow as in other search engines)

I'd like to be able to search emails with attached files (or without attached files)

Hi. You should compile a dictionary of every email content to provide a client side search like mkdocs. All the processing can be done client side. The dictionnary can then be stored encrypted on your side. https://squidfunk.github.io/mkdocs-material/setup/setting-up-site-search/

You should also implement openid and connect your forum with it and try to block spam. Proton OpenID should be available to authenticate all app on the Internet that wish to use it.

The search on iOS is pretty trash compared to Apple Mail or GMail apps, please bring advanced search from Desktop to iOS as well

Can't believe this still doesn't have the capability to specify a Folder to search in. Who doesn't have folders??

Really, it's amazing this capability wasn't put in at the very beginning as it's super obvious!

And exclude Trash by default, it's just common sense!

Ditto plus operators like has:attachment or has:pdf from:<email address> or subject:<the_subject>

If I'm standing on a folder or label, I'd like it to be selected as default search place.

Yes, I'd like to exclude Trash by default too

Would be important to enable more complex searches, like "in:labelA and not in:folderB"

I often cant find specific emails, if i cant remember the name but only keywords. Like last time I used the word bicycle a lot, but could not remember the email. I could not find it. Or contacting proton and i could not find it. I am not sure, if I do something wrong, but that really is difficult, as I have many emails runnig now on protonmail and i cant find them again :/ I would find that very urgent matter (apply to app and webbrowser)

Yes, please. And add "smart' spelling; as it is, one letter off and the search fails. It's too basic, and often fails to return any results even though the item is there when searched manually. And it's too slow. I also have the paid plan, but in may respects I miss some of the free Gmail features.
