My complaint about Bing for technical querying is that when I tell them I want an exact phrase by wrapping it with quotes, it doesn't always believe me that I really do want that phrase to appear in the result page.

Some of those other operators look promising, though. I'll have to try them out.

The "near:" operator looks very useful.
