Please make it so Proton's in-browser webmail has the ability to search using operators, the way virtually all other e-mail providers and clients allow (by typing things like the following into the Search bar):

• from:[name/address/domain]
• to:[name/address/domain]
• cc:[name/address/domain]
• has:attachment
• before:YYYY/MM/DD
• after:YYYY/MM/DD
• subject:"[text in subject]"

This is a basic (and absolutely crucial) feature for an e-mail inbox to have, and all other providers have it. I do not want to be running multiple searches using the clunky mouseclick menu, as that is highly inconvenient and wastes a lot of time.

Please add this feature! I have been on premium for 2 years and have still not seen this implemented. It really makes search difficult to use and I don't want to have to install a client just to search my e-mail.
