Looking for special characters in Google [closed]

Do you know how to look for special characters with google...?

I'm looking at bash code and there's the ## operator. I would like to know what It does but I wasn't able to figure out a way to protect the character (I'm not sure it's even possible).

This is particularly annoying when you're looking for some code patterns, some characters are always ignored.

Solution 1:

Google strips most punctuation from queries, as described here, so it won't help you with the bash syntax.

It's very easy to search for the string "##" in the bash documentation: Just run "info bash", hit "s", and enter "##" as the search string.

Solution 2:

google strips puntuation, imho, because:

• it's somewhere used for special search (chars like - to exclude, +to add and 10..20 to specify a range)
• to avoid spammers to get email addresses (characters like @ or .) in my experience, it's even impossible to escape special characters. the only solution I found, by now, is using yahoo http://it.search.yahoo.com/
