Hi! I think I'm having the same problem :)
I posted my game 1 day ago, but it doesn't show up in search: https://sexgamedevil.itch.io/juliet-ragdoll
Some games are indexed fast and some are not.
There is no official documentation that tells you exactly why but from what I have read on the forum.
Free games from people who already have other projects uploaded are usually indexed quickly.
First game, or if the game is paid or if something calls attention, surely it enters a queue to be reviewed manually and apparently that queue is the one that takes a long time to be reviewed.
The other thing, it is better that you ask your questions in your own thread, around here the only thing you get is to obstruct any answer to the person who opened the thread.
