I have just used the Mocavo genealogy search engine for the first time, even though it has been online since 2011. I used the UK version, although there is also the option of the original US version. First impressions are very positive.
Mocavo is a search engine that has been designed specifically for genealogists. A basic name or place search will very quickly return a collection of results from genealogy websites, blogs, message boards, and more. The search engine does not just look for the most up to date information as Google does, meaning that in theory it should be much more reliable at producing results which are useful and relevant. Even if a genealogy website has not been updated in months, the information it holds will still be crawled by Mocavo. That information could be just what you are looking for.
Mocavo requires the creation of an account to be able to perform a search. A name, email address, and password is all that is required. A basic account is free, but there is the option of signing up for Mocavo Plus at $79.95 per year. This will give you some extra features, the most useful of which is the ability to perform advanced custom searches.
The makers of Mocavo claim to have over 6 billion names in their index. Users can upload their own family trees and research documents, and share information with others. There is a real community feel to the site, and there is also a blog with many interesting and informative articles.
All in all I've been initially very impressed with Mocavo. I need to try it out further before I decide whether or not to upgrade, but I'm inclined to think that it will be my search engine of choice when carrying out genealogy research from now on.
