Andreas suggested a more robust museum search. It's hard to say "no" to a guy who does so much around here. Check it out!
- search options: all these words, this exact phrase, any of these words, none of these words
- filter results by: section, mechanism, inventor, producer, year

- a "Refine Search" function on all search result pages
I sure enjoyed playing with it, I hope you do too.
