There is a syntax you can use to search for entries that contain both A and B:

>+A +B

It is annoying but it works.

This could be a good first contribution to Bitwarden for me or anyone really.

Do you mean the browser extension search feature?

Thanks for pointing it out.

Just checked, and its indeed doing this nonsense in the browser extension (on firefox). Its implemented sensibly in the Android app, and I haven't tested the website vault viewer or the desktop app.

Thank you for checking and reporting back.

I never touched Bitwarden project but I hope I or someone could contribute to a better search in the extension.
