Yesterday, we reported on a pretty serious Google Product Search bug. That bug was so serious that searches for products like xBox returned no results.
Google Product Search representative, Albert, said yesterday that they fixed the bug:
Just wanted to give you all an update -- we pushed out a fix earlier today, and you should no longer be experiencing the issue. Anyone still having this problem?
If you see more issues, let Google know.
