Something strange is going on...

I was doing searches within my own portfolio to make sure I wasn't submitting a duplicate asset and, despite using keywords I often use (woman, fashion), I kept being told nothing could be found and to "try your search outside of portfolios."

So I got more specific and entered the exact title of one of my assets (second one from the left at the bottom with the pink and blue makeup). It showed up, but I also got the notice that nothing could be found and to "try searching outside of portfolios," as per the example below. 

I've been seeing posts of people with drastic drops in sales, and from others having issues finding their own images in the database. Is something broken?
