I use a lot of search engines since I am a very big search engine fan. Some of them aren't all that good, but others aren't all that bad. Some have features that are different from what a person is used to seeing.
There is a search engine I've been using for several years. It isn't my first choice but I do like to test it at times just to see what type of search results I will get. I am often pleased with the search results.
Some people have heard about it and many haven't. It is actually a lot more successful than most people realize.
The search engine I am talking about is Gigablast
Gigablast
The general public can use Gigablast. In addition webmasters can display search boxes that are powered by Gigablast. There is also site search, custom topic search, hosted search and XML search feed.
Gigablast has a very impressive list of clients which include: CNET.com, Snap.com, mamma.com, Quepasa Corporation, Browsercast, clusty.com, eurekster, find.com, MonsterCrawler.com, deepy.com, eWoss.com, zimply.com, FindTarget.com, everyclick.com, SweetIM.com, effectivebrand.com and ixquick.com.
