Site bug: I'm sorry that the year's first update is about a bug, but there it is. There's an error in the search function which causes search strings with multiple words (e.g. Zork II) to fail.
Workaround: put a + between the search words - Zork+II will function.
It's not ideal, but it works. I'll get the search function fixed a.s.a.p.
