11.3 Is there a quick way to search for information on Debian GNU/Linux?
There is a variety of search engines that serve documentation related to
Google Groups: a search
engine for newsgroups.
For example, to find out what experiences people have had with finding drivers
for Promise controllers under Debian, try searching on the phrase Promise
Linux driver. This will show you all the postings that contain these
strings, i.e. those where people discussed these topics. If you add
Debian to those search strings, you'll also get the postings
specifically related to Debian.
