The Universal Meta Search and Discovery Engine

PolyMeta was a meta search engine, federated search and clustering engine that enabled its users to browse various information resources on the web and list their results in a results page sorted by relevance.

PolyMeta was developed by WebLib Search Solutions (now Precognox) from Budapest, Hungary. Precognox is still active today (2019) in the field of enterprise search solutions. Also in the past PolyMeta was already used with other offers like Scienceroll. A showcase of the search engine was offered from 2007 to 2012 under the name "allPlus".

Ask, Bing, Cuil, Google and Yahoo were searched. Via "Select sources" the user can change the default settings and decide for himself which search engines should be included in the search. "Show hits" shows how many results each search engine contains. The results of the first results page of the search engines were evaluated and ranked according to their own criteria. Unique results are highlighted. Basis of the result analysis is a clustering system which the user also got displayed. Later, PolyMeta showed a blended result page, which contained news, blog and video previews as well as web results.

Phil Bradley (2009):»PolyMeta is a search engine that someone mentioned in a recent blog comment, and I went along for a look. It searches in the areas of Web, News, Images, Twitter, Video and Blogs. It pulls content from Ask, Bing, Cuil, Google and Yahoo. This could be expanded out to include another 3 engines through their 'sources' option. Choices differed according to search option chosen, so News included content from Topix for example. It also provides a total number of results from each engine together with a click through to go directly to the search engine site. Content is gathered from the first page of SERPS (which given that Bing has a larger default for the number of results on the home page would seem to give it a slight bias), and then arranged in some way that made no sense. I did a search for a hashtag for a specific conference, and the top result had been found by Cuil, second result had been found by Ask, and the third result by Ask, Google and Yahoo. Unique results are highlighted, which was a nice feature. Information was displayed in a triptych with clusters/sources on the left, results mid screen and images on the right. There's also a 'did you mean' option which it's culled from Google. The web search was ok, but having recently looked at Scoopler, it was a little lacking in currency, and didn't hold up any better when I actually checked out their Twitter tab. News was ok, but couldn't hold a candle to the more specialised Silobreaker. Image search pulled content from 10 sources, but was quite lacking in detail - just the image and source, with no further details. The video option was also ok, but again not as good as my preferred option of Trooker. The blog option only pulled content from Ask and Google, which was disappointing. In summary I think that Polymeta almost makes it, but misses out all around - it's just not quite good enough at any single thing to pull it out of the masses, and doesn't have any kind of unique feature to overcome its other limitations.« Source

2015: Today PolyMeta offers a blended result page, a Topcs Graph (clustering) function, a topic search and more. Source

Mon 18 August, 2008: »We have added results from the new Cuil search engine to the web results on PolyMeta. Cuil in itself is not too strong yet, however because of the different ranking algorithm it can give you very useful additional results in a meta search, what other engines did not retrieve.« Source
