Yippy goes back to two predecessors, Clusty (2004-2015) and Vivisimo (2001-2006), the latter based on web search technologies developed by researchers at Carnegie Mellon University. All three search engines are meta-search engines that use clustering technologies to automatically group content. These groups are listed on the results page so that the user can dive deeper into the results thematically. Yippy works closely with IBM and has a license to use Watson Explorer (a sophisticated cloud clustering technology with categorization, deduplication and relevance methods). Yippy itself also developed the so-called Yippy Mac Daddy Browser, which allows mobile phone users to use the Internet very quickly.

Currently (November 2019) the contents of Bing and Bing News are used for the Yippy web search.

CIO Applications: »Yippy’s technology was born out of the Carnegie Mellon University. In 2010, Yippy, in its early years acquired an unlimited world-wide perpetual license for software known as Velocity— considered as the most powerful search engine at present—from Vivisimo. Vivisimo was later bought by IBM, leaving Yippy as the only other company with the exclusive and transferable rights to Velocity which is the same software that powers IBM Watson Explorer.
Yippy Search Appliance is unique because of its wide range of unmatchable features. The engine's unique clustering technology enables users to navigate big data sets by topical categories dynamically to derive meaningful relations. The search engine can cluster or data shape categories on the fly through hierarchical agglomerative algorithms, empowering a user to achieve quick results and familiarize with concepts in data sets that were previously unknown. « Source

Paul Gil (2018): »Yippy is a Deep Web engine that searches other search engines for you. Unlike the regular Web, which is indexed by robot spider programs, Deep Web pages are usually harder to locate by conventional search.

That's where Yippy becomes very useful. If you are searching for obscure hobby interest blogs, obscure government information, tough-to-find obscure news, academic research and otherwise-obscure content, then Yippy is your tool. « Source

Interview with Michael Cizmar (2016): »Yippy was founded in 2009, and has been essentially in stealth mode for a number of years, developing an impressive array of proprietary technologies. Obviously, Yippy’s license to use Watson Explorer (with its sophisticated cloud clustering technology, as well as categorization, de-duplication, and relevance methods that provide an excellent search experience) is a key part of Yippy. In addition, Yippy has independently developed a very impressive technology known as the Yippy Mac Daddy Browser, which enables users of satellite communications technology to browse the internet at speeds that were previously unimaginable.
IBM Watson Explorer’s beauty is its vast array of use cases. IBM has done some spectacular things with this search and clustering technology, and so have we. IBM is one of Yippy’s largest shareholders and we have a close working relationship.
Yippy’s secret sauce is great technology and great engineers. However, one capability that might be overlooked is Yippy’s robust connector framework, which we have recently integrated with MC+A’s connector capabilities. Together, we have the ability to ingest the common enterprise file types, including structured database content and XML documents. Yippy has a connector advantage because we are not handcuffed with the aging Oracle Outside In technology or Salesforce-owned EntropySoft filters.« Source

Saikat Basu (2017): »Yippy is bit more than a traditional search engine. Some of you might remember it by its old name – Clutsy. And as the old name suggests, it de-clutters search results by tapping into several search engines. It then combines the results and groups similar results into groups. You can shovel deeper into your search with the group keywords on the left.
The meta-search engine also filters out undesirable results, so you can recommend it as a good educational search engine for kids.« Source

Julia Sowells (2018): »Yippy in fact a Metasearch Engine (it gets its outcomes by utilizing other web indexes), I’ve included Yippy here as it has a place with an entryway of devices a web client might be occupied with, for example, such as email, games, videos and so on.
The best thing about Yippy is that they don’t store information of the users like Google does. It is a Metasearch Engine, and it is dependent on other web indexes to show its results.
Yippy may not be a good search engine for people who are used to Google because this engine searches the web differently. If you search “marijuana,” for example, it will bring up results that will read ‘the effects of marijuana,” rather than a Wikipedia page and news stories. So it’s a pretty useful website that can be good for people who want their wards to know what is really required and not the other way round. « Source
