Effective Googling, forcing auto-excluded sequences
I've been looking for a really good on googlefu, but all the ones I've found have been pretty useless (such as explaining the * operator). I have two basic questions:
1. What's the best guide you've found that explains advanced googling techniques?
2. How do I force google to include characters/sequences that they automatically strip? For example if you use the search term $HOME google strips the $ and you end up with a bunch of results about houses, home depot etc. I tried \$HOME, $$HOME, "\$HOME", "$HOME", "$$HOME" and all those are the same as searching for HOME.
