This is NOT completed. If you happen to use Proton in, well you know...a PHONE. Then this is NOT working. The mobile browser doesn't offer the option to download the email contents at all. If you force desktop mode, you can trick it to ask for it. It even asks for permission. But then it does nothing. And if you switch back to mobile mode, the 'non-working feature' disappears altogether again.

And in the app...well this is not an option. At all. So no, this is NOT completed. Please reopen.

1) Given the comments by mobile users, this should be re-opened. (For example, on the go I am using mobile. I want to check an appointment. 10:1 the subject line will contain the word "confirmation," the sender will be some third party, and the actual airline or doctor will only be in the body

2) I was about to complain about the enormous download required to search in message content on my laptop, but that seems to have improved

The implementation of this feature is pretty bad for users who imported their message history and it lacks mobile support. I think this item needs to be reopened.

When majority of users use mobile phone to access Proton apps, Proton decided to introduce features that are only available on desktop and thought they "completed" what users asked for. What a joke.

Everyone please cast your vote to this request.

This feature needs to be added to the iOS mobile app. It's impossible to find most emails with search.

When is it coming to Mac OS apps? The option is there, I have it turned on, but it doesn't find words in the email body.

When it is coming to mobile apps? The search on iOS is abysmal

Yes, its absolutely required in mobile apps too. it is driving me crazy… Also i am not sure the search on the Native Mac/Windows app works correctly. I find matches in body content but i have an email marked with an label, which contains the keyword but does not come up during the search. So currently not very trusted in the search..

this isn’t complete - it’s only available in browser and not on the mobile apps.

this is critical, table stakes capability that massively impacts our ability to find emails

When I buy something (licenses, subscriptions, goods, etc.) or have an appointment (reservations, doctor's appointments, etc.), more often than not the receipts, confirmations, or order updates come from a third party (a payment processor, parent company, CRM, central front desk operating under a different name, you name it) and the email is almost never titled with the words I'm looking for (product/good name, doctor's name). The mobile Proton app (iOS in my case) doesn't even have the ability to build the annoying local database web browsers use for body text search.

Proton Mail PMs, understand this: when I have to look for something without access to my computer and that is time-sensitive, I am out of luck. Even with desktop web browsers, it takes time to build a local database. I've experienced this inconvenience multiple times and while I hate to admit, I regretted moving out of Gmail completely. Not sure how much remote compute cost you are concerned about incurring, but the additional cost implication doesn't justify the paid subscription if you have the right engineering resources.

When will it be possible for users to enable this feature permanently, rather than having to wait for a long download every single time? It's untenable to have to manually download every single message sent or received in orderto make those messages searchable. Please address this! Search is such a critical feature, and it's still not all the way there.

I've been testing switching my professional email to Proton Mail. It has not gone well. Without the ability to search the body of emails, emails older than a week are so turn into compost.

This has been fixed by the Protonmail team for Plus users, thanks a lot! You can now search message bodies https://protonmail.com/support/knowledge-base/search/

Protonmail search is quite simple. 9/10 my search queries fail to find the relevant emails. Nowaydays we all recive so much mail that is not useless but also not so important to be save in a new folder.

The only solution is to leave it in the archive or inbox with thousands of other emails.

Please. An ealthy email workflow is to simply archive all the "taken care off" emails so your inbox acts as a to-do list.
This is only possible if you can then find back achived emails with a quick search.

Bridge is not the solution, it should be possible from ProtonMail app or the web application. It's been possible in Tutanota for years, why not here? Thanks

I am horrified that this feature isn't available :(. Even my e-mail from a local provider that I have since I was 6 years old has that.This really makes my life difficult now, such feature is more than important.

It looks like this was just added to Professional plans - fingers crossed for Paid!

I am ProtonMail Plus subscriber and I am super happy with the service. My only complaint time and time again is the search functionality which is borderline tragic. Now my parents are wondering if they could also have encrypted email and honestly if the search was at least average, I'd just subscribe to Visionary right at this second, but as it is now, it is a very hard sell.
One thing is the inability to search trouh email body, but even search trough subjects is wonky. I was for example buying a second-hand item online and was talking with 3 possible sellers. All email threads had the item name in subject, but one had it in slightly different format (without a dash) and it was just such a pain to always do two searches to find these conversations.
Really, please improve the search.

Honestly after using ProtonMail for a couple of years now it hasn't bothered me as much, but it would be great to see this feature implemented.

As a side-note (tho I am using only Webmail interface) you can also use ProtonBridge on Windows/MacOS with Outlook/Mail apps which gives easier access for search and organizing features. As well on mobile I am using Blackberry Hub+ Inbox app (Android) to easily search through all my Telegram, Protonmail, social media messages
