Hmm. Sometimes it would be nice to disable Regexes so you don't need to escape all characters in the string, if you do a keyphrase search looking for full matches.

Who's going to be the first to spot internal Google code? :-)

Here's a good start:

http://www.google.com/codesearch?q=prod.google.com

Code with @google.com email address

Comments in code for "Stupid clients"

ehm... what about Koders.com ? ....... veeeeery similar

This looks good, a while back I was looking for "Thread.new" examples in Ruby and did not come up with much. There seems to be a good selection here – but only one that would have solved my question.

Now will google start to take over the "code search" keywords and put their software first ? Or are they keeping to the do no evil theme ?

To my surprise, I already used Google code search about a dozen times today while programming... this is incredibly handy!

<< Now will google start to take over the "code search" keywords and put their software first ? >>

Probably, because thousands of people on the web will already have started linking to them using the words "code search" now this has been relased...

Besides, everything in the Google network gains PageRank *very* fast... e.g. Google Labs has PageRank 9 and links to it, the official Google Blog has PR9 and links to it, and so on...

Anyone want to make a bet when [code search] results in Google Code Search as #1? :)

I can't wait till someone makes an eclipse plugin for this like the Koders plugin.

Not shown on the advanced page, but you can get more than 10 results by using &num=100 on the url. Given the poor relevance ranking for code, you really do need to see as many results as possible at once.

What about email harvesting softwares?
Simple regexp resulted in millions of name+ email ids.

this is awesome

Terrible first impression. I searched for Tapestry and didn't get a single hit to the Tapestry 4.0 in the first few pages. The first page was all old and outdated code. Hmmm

its amazing what programmers put in there comments..

they already have an ad about it at the top.

Hmm, I can't see that, might be US-only...

This is awesome. Regexps (or at least strict character interpretation) in normal search would be even more awesome. Spammers can already find millions of email addresses very easily, it would probably make little difference.

Google is blocking certain code searches that reveal passwords (as linked from kottke.org):
http://www.google.com/codesearch?q=+file:wp-config.php+username&start=10&sa=N

50 results, but only the first (with a default password) is listed.
