TromboneChat

This seems like a stupid question, but how can I search on TromboneChat for threads about M&W horns? When I try to search on "M&W," I get a message telling me

"The following words in your search query were ignored because they are too common words: M W.
You must specify at least one word to search for. Each word must consist of at least 3 characters and must not contain more than 84 characters excluding wildcards."

There must be a simple way to get what I'm after, but it eludes me. Thoughts?

Google doesn't currently index TC, but Bing does. I'm not an expert in Bing queries, but searching with this seems to work:

It will just try and come up with any word with M or W in it, so it won’t let you….you could try something like ‘M&W 322’ or another model number.

Likewise I cannot search 4B or something King because it only contains 2 characters.
maybe is there any plan to re- enable 2 character search function..??

AtomicClock's Bing method works, thanks very much. I didn't try it for 4B, but might be worth a shot.

Thanks much for everyone's response, much appreciated.
