Is eBay search broken?

Often I use the "-" followed by a list to remove certain words from the listing. For instance if looking for generic mercury dimes not graded, the search looked like this:
Mercury Dimes -(pcgs,ngc,anacs)
But now when I try to remove items, the search comes back with 0 results. Did they do some kind of "improvement" that makes the search function now useless?

I used the selective search for something else yesterday and it worked for me...Cheers, RickO
Just did a seach in ungraded and got 29K+ hits. Put Mercury Dimes in the search bar then selected Ungraded. Normally I would have seleceted PCGS.
FC Cloud is correct with the sequence. you missed the space and no coma. I believe you can use 5 or 6 - or -
if you go "mercury dime" that means that this word or # must be there exactly as written
Looks like it's working today. Just wanted me to start a thread about it, haha.
It's fine for potholders.
its been broken since 2011
Altho it works, it ain't working right .....
