Highlight items using keyword "rarity" doesn't work

If I want to search for items in my stash tabs which have an influence on rarity, you would think the thing to do is search for the term "rarity", but no, this simply highlights EVERYTHING no matter which tab you are searching in.

Yes, because you can filter items of a specific rarity. I do that when rolling a tab of alched maps for mappers to scour magic maps and then alch all normal maps.

I'm not at home to test, but you should be able to expand the search as the full modifier is called "% increased rarity of items found", so there are plenty of other text searches that work besides just "rarity".
