Google++
Is this a new development? I only just ran across this but this is a huge improvement to Google for me: Google now considers some punctuation part of the word you're searching for and will match only words similarly punctuated.
This is significant for searches like C# and C++, which previously would have been truncated to just the letter "c".
I tripped across this searching for an update to Spy++, which seems to always hang my box so hard I need to reboot. I was expecting to have to pepper my search with things like "-espionage" to narrow search down to the topic I wanted, but no, the results were actually relevant to the Spy++ tool.
Alas there's still no update available for Spy++.
