Thanks for the reply.
But I am curious that why HalfLight could be searched?
When I published HalfLight, I didn't upload an executable file. (I uploaded a video instead)
Then, I could search HalfLight in the search bar immediately.
So seems the mechanism of searching is not based on the executable file.
I check both publishing setting of my games, there are no differences.
(except I didn't set the link of the trailer for Heroine Anthem Zero...maybe this is a problem?)
I also searched and checked other games, their games are searchable and are published successfully with only pdf/doc files instead of an executable file.
If there is any other way to fix this issue, that would be great. Thanks
