4.12. Browsing Groups
From the main Google Groups page, you can browse through the list of
groups by picking a hierarchy from the front page.
You'll see that there are subtopics, sub-subtopics,
sub-sub-subtopics, andwell, you get the picture. For example,
in the comp (computers) hierarchy,
you'll find the subtopic
comp.sys or computer systems. Beneath that lie
75 groups and subtopics, including comp.sys.mac ,
a branch of the hierarchy devoted to the Macintosh computer system.
There are 24 Mac subtopics, one of which is
comp.sys.mac.hardware , which has, in turn, three
groups beneath it. Once you've drilled down to the
most specific group applicable to your interests, Google Groups
presents the postings themselves, sorted in reverse chronological
order.This strategy works fine when you want to read a slow (i.e.,
containing little traffic) or moderated group, but when you want to
read a busy, free-for-all group, you may wish to use the Google
Groups Search engine. The search on the main page works much like the
regular Google search; the differences are the Google Groups tab and
the associated group and posting date that accompanies each result.The Advanced Groups Search (http://groups.google.com/advanced_group_search),
however, looks much different. You can restrict your searches to a
certain newsgroup or newsgroup topic. For example, you can restrict
your search as broadly as the entire comp
hierarchy (comp* would do it) or as narrowly as a
single group such as comp.robotics.misc . You can
restrict messages to subject and author, or restrict them by message
ID.

the date searching. With Google Web Search, date searching is
notoriously inexact;date refers to when a page
was added to the index rather than when the page was created. Each
Google Groups message is stamped with the day that it was actually
posted to the newsgroup. Thus, the date searches on Google Groups are
accurate and indicative of when content was produced. And,
thankfully, they use the more familiar Gregorian dates rather than
the Google Web Search's Julian dates [Hack #16] .
