Is the search box's minimum number of characters something we can set to, say, 3? It is unfortunate that we cannot search for terms like "ps2" or "wii" (for instance in the marketplace) as these searches come up with no results. Additionally, these short search terms are omitted in a search for a string of terms, it seems - an example would be "wii homebrew" will only search for "homebrew" in my experience, and will ignore "wii" as it is presumably not enough characters.
Three characters is too few - it produces too many results. You don't need to search for "ps2" or "wii" - be more specific. wii AND homebrew - works "wii homebrew" - works Standard search terms, really. Or use Google: wii homebrew site:assemblergames.com
Derp. I should have remembered trying operands/quote marks. I've been really sloppy recently, eh? Mainly I was trying to search the marketplace for a single platform. All is sorted, Thanks retro.
