Searching for "body armour" in stash

I have tried quite a few different keywords to search for all items that go into the "body armour" item slot, however I cannot figure out what to search. Im not even sure if it is a bug, or if im just not typing in the correct keyword.

You can only search for what is written on the item. Unless I've just been a complete tool these past years.

It's irritating, but something you just have to live with, same with searching for 'Belt' it doesn't highlight the rustic sash, etc. Only those that have a belt in the name.

More advanced searching would be lovely. Like itemclass:xxx or basetype:xxx. Also basic operators like OR (e.g. by comma, "tier:5, tier:6") and < > (e.g. "ilvl>80"). The OR operator would be a workaround both for "lesser/greater than" operator and class/base, because we could use snippets like all armors classes separated by comma. Or by semicolon.
