Released last thursday in Beta version, Yahoo Alpha is a new search engine designed to specialised search : same principle as Google CSE (Custom Search engines) we already talked about here previously, but Search is extended to different tools such as FlickR, Wikipedia, or even Youtube and the interface is in Ajax. Last test done today gave me the following error message "We're very sorry. Gremlins have stolen our ram. We sure will miss them. " .. ;) So Let see later !

Interesting tool, released about 2 weeks ago, qualified by Tim O reilly as "The next big thing", Yahoo! Pipes is one of the data mashup environments that can really change the way we make the Web. See Existing pipes ...

Do you search information about Google with Google ? you could maybe use Google Inside, a Google Co-Op CSE (Custom Search Engine) designed for that purpose (expert system). I ve uploaded the interface in the right menu and you can use whenever you like.

A co-op search engine is typically a Google Search onto specialised sites. A way to find the List of all the Co-Op Search Engines would be to submit this request onto Google.com : "inurl:cse site:google.com inurl:coop"

Other tools can be associated to perform a deeper or more specific search : Subscribed links ; OneBoxes...
