"Search for games or creators" should read: "Search for projects and creators and suggested tags". Some of the hints here are not very helpful, if taken at face value.
Just copy a longer asset name and search for it in search box and then search again but leave out some of the title, to see what is happening. Also look at your search url.
On the other side of the issue, the names of assets are often not names, but descriptive. "Baba Is You" is a project name. "rpg pixelart cave tileset [16x16]" is a description and a title, but I would not call it a name.
