Searching The Usenet Universe
The subject categories on Usenet created hierarchies of topics—all nine of them—with the purpose of separating topics of discussion in a clear manner to keep unrelated information from being presented to the reader who was basically interested in a particular topic. This also worked so replies to a specific subject remain relevant to the group order. Threads then make it easy to follow a single discussion. However, when you want to search for a specific topic such as coin collection you would need to sift through thousands of downloaded headers to check if there was something of significance in a group and go over the chore again for each individual group. Just imagine what it was like performing this difficult exercise during the dial-up days of yore. In February 2001 Google bought Deja News and started archiving the past two decades of Usenet activity, all one billion messages, and renamed it as Google Groups. Like its origin it retained the obscurity of newsgroups when it deliberately did not include Google Groups in its homepage. Fortunately you could search this immense archive through its Advanced Search. Options to assist locate information such as author, subject and dates are possible. One more good thing about this method is its specificity. You could just type any newsgroup name and get posts from that group right away. Or you could be more detailed by filling up your search terms and be directed to the posts you need. As vast as it is, Google Groups is restricted to text posts only. Most Usenet readers like you and me want access to binary files, and Google just cannot give you that. Here come web based search engines that offer this functionality for a premium. Examples of Usenet search engines are Binsearch, Newzleech, NewzBin and Binnews. Most of these search engines produce .nzb files after each search. .Nzb files are xml files that contain the newsgroup name pertinent to your search which, when used with a compatible client tells you where to find the essential bits of files to piece together a video, mp3 or software. This proved to be a breakthrough for binary files circulation and paved the way for these web based search engines to present an indexing of posts and allow for easy searching. .Par and .par2 files were also introduced to allow file pieces to be reconstructed. These pieces can be rummaged through heaps of posts via .nzb files from search engines. One thing clearer about web based Usenet is that it presents a more orderly line up of newsgroups that was not observed previously. Categories and sub-categories of topics are in hand for easier navigation of this thriving online community.
