Element message search - filter by properties

[throwabird]

Your use case

What would you like to do?

I would like to be able to filter the search results by certain properties similar to how discord does it.
For reference here are discords properties:
from: user
mentions: user
has: link embed file video image sound sticker
before: date
during: date
after: date
in: channel

The last property could also replace the 2 separate tabs "This Room" and "All Rooms" which are currently in the element search or make the button add the filter in the search bar.

Why would you like to do it?

There are several cases where this can come in handy - to name a few:

• Searching for a particular image has:file or has:video or even has:link
• Filtering search results by people from:@user:matrix.tld
• Looking at results further back before:date

How would you like to achieve it?

The current Element application (desktop) already offers a search feature which stores the chats locally. The search query would need to be improved with such filters and possibly store more (meta)data to archive the aforementioned features.

Have you considered any alternatives?
