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.

Please, do not disrespect the moderator.
I understand your anger, I am also having issues with the platform that make me feel very bad and frustrated, but the moderator can only relay our complaints to the administrators to try to help us. Let's be thankful that at least he responds quickly. What will we do if more people start bothering him and he ends up stopping responding to our questions and trying to help us? Even if his answers don’t always reassure us, let’s thank him for helping.

Crazy how this keeps happening. Clearly their "algo" is broken in some strange way.
