When performing a search there's a list where you can select certain prefixes to filter by but there's also an option titled "några" (some) and if you don't uncheck it the option negates all other selected prefixes. In this particular case I assume it's a bug but I don't really understand the purpose of the option as there doesn't seem to be any real use for it?
I'd also suggest changing "sök tråden" (search the thread) to "sök trådar" (search threads) to avoid confusion.
