Often when people post topics about search results it’s because they’re trying to optimize their game’s placement on the results page
Of course, I am worried about my game showing up when people look for relevant keywords. I am quite happy with my tags, my humble little game is faring quite well for now on Browse. It was then that I decided to check how it shows up in search and found out a lot of people were tracking ahead because they did something like: Game Title (Tag Tag Tag) or just: Tag Tag Tag as the game title.
I am always looking for ways to give my games a better chance, but I do draw the line way sooner than a lot of people. Stuff like this makes me wonder if I am just the stupid naive one. I frankly don't want to keep considering naming a game around SEO terms, my alternative was starting this discussion.
The search autocomplete will push someone trying to type a topic name into the search bar to the respective tag name.
Not for tags below ~200 games. This also seems to be the reason some tags do not autocomplete anywhere on the site like redonihunter just pointed out. I get that there probably should be a bar that tags need to clear to show up, but maybe it should be lower.
To give an example, Itch hosts Toe II Toe, the most beautiful pixel art boxing game I've ever seen. Writing "boxing" on Search will never show it even if you scroll to the bottom, because it's not on the title and it's not on the short description/tagline(The author decided to use the term Slugfest to describe it in the tagline. Can't blame them, it's a fantastic term). "Boxing" will also not autocomplete either on Search or Browse.
The search bar is for discovering content by name.
This idea was reinforced by the link you provided. "Direct title search: Someone is looking for something specific and types in the name of the project". But from my testing, it's not only the title, it's also the short description/tagline, which leads more people into just filling that with tags and getting ahead in search results.
