They broke it ages ago when they made it do “stemming” of words — so typing “fart” would also allow it to find “farts”, “farting” etc.

It’s made it more useful for the general case where people type slightly the wrong thing, but for finding more specific items it’s definitely more painful now.

That and that there are loads of sites trying to work the system to push themselves up the ranking, which they don’t appear to have worked out a way to automatically remove from the index (so it takes a while).
