I had uploaded a my game long time ago but it doesn't showing up in searches. I don't know what's the problem ?

You read the guideline?

Your game doesn't have a proper description, it's marked as a windows game, android game and you only have the HTML5 version, etc.

It might have been placed back in the review queue after the latest change. If it takes much longer to be indexed, see the rules of this category for what to do.
