You're right, my bad. I was looking at the wrong field. That said, changes you've made recently can also cause your games to be placed back in the review queue. And which three pages, out of the six games you have published? I looked at the last one, and you're right, but see above.
To answer the question in your post title, site search is intended for players to easily locate games they already know about. It's not a marketing tool. Our admins are asking creators to do their own promotion through other channels rather than rely on itch.io for that.
Both things I've just explained are mentioned in the unofficial FAQ you said you've read.
