Search aggregation is hot. If you haven't come across the term before it is a service that takes a search string and runs that search on a selection of sources such as search engines and archives and returns a single page of relevant results. Make no mistake, search aggregation is quite a complex thing to do and its potential, given the myriad sources on the Internet that can be searched, is huge.

A subcategory of search aggregation is “recency search” wherein the only the most recent source content is returned. Our first recency search aggregator is Very Recent (tag line: “The Buzz Search Engine”).

The first thing you’ll notice about this service is that it is ugly. Definitively, brutally, unremittingly ugly. Why? I have no idea. It is almost as if the author chose to produce something that only they, its parent, could call beautiful. In fact this site is a good candidate for modifying with Greasemonkey.

Another odd thing about Very Recent is that there is no information about the author or the company, no way to contact them, no details of the service or what sources it uses, and the only additional information on the site is a privacy policy that is about as unrestrictive on what they do as can be crafted by devious lawyers.

A little research revealed that Very Recent was created by Tom Churm who also authored (among other services) the interesting free service RSS2PDF that takes RSS or Atom feeds or OPML files and generates a PDF file from it.

So what is good about Very Recent? Well, it works. It returns useful data and is very fast in comparison to other similar services.

According the Search Engine Land blog the sources searched by Very Recent include Twitter’s Summize, Google Blog Search, Technorati, Flickr, Yahoo News, YouTube, and Digg. The default home page of Very Recent shows the latest headlines and a list of search terms from Google’s Hot Trends USA, which when you click on one of them, launches a search of that term in Very Recent.

Also according to the Search Engine Land posting Very Recent is, itself, very recent although the developer hasn’t bothered to label it “alpha” or “beta” and it appears more experimental than a product in development. Even so, the service is useful as it is.

Not so experimental is Addict-o-matic another recency search aggregator with a lot of polish. Its search sources include Google News, Google Blog Search, topix, YouTube, technorati, Yahoo News, Blinkx Mainstream Vid News, Flickr, Newsvine Tags, icerocket, Delicious Tags, Digg, Addicto Top Blogs - Bloglines, Truveo Video Search, Bloglines, Yahoo Top News Sources, Ask.com News, Google News Images, Twitter Search, Yahoo Web Search, Wordpress.com, Live.com News, Wikio, and Twingly Blog Search.
