Hi!
The general Search box was what I was using (top right corner of interface)
I typed in the following:
Readers Digest
and expected to see Reader's Digest Q371820
but it did not appear.
Today I just checked again the same scenario, as I typed this email.> and now it does appear.
Yes, this is how it should work. There were no changes lately, AFAIK, but it is possible that you hit some glitch or maintenance on your previous search. If that happen again, please tell me when and with which search string /URL, I'll try to investigate.
