Meta-Search or Clustering

I came across this interesting way of search algorithm, when I was doing my internship in (Indian Institute of Information Technology & Management Kerala) IIITMK's R&D wing in Thiruvananthapuram .. I was really amazed by this, even we (my fellow interns) used have sleepless nights in lab of IIITMK discussing about this ..hey we even charted out a business plan :) .. but I lost track of it when I got placed in software biggie in blore .. really lost track of research interests .. but now I finding time and mind to do it again ....

To find out what meta_search or custering is : do a simple search for keyword "chips" in Vivisimo http://vivisimo.com/search?tb=vivisimocom&query=chips and Carrot2
http://demo.carrot2.org/demo-stable/search?in=Yahoo%21&q=chips&s=100&alg=Lingo&opts=h and compare the results with those given by Google http://www.google.co.in/search?hl=en&q=chips&meta=

Interesting right .. meta-search algorithms tries to identify clusters(similar contents) inside a one big clusters .. (cluster inside clusters) and groups or labels them in GUI. Lots of proven algo. are there like fuzzy means, using a data structure approach like Suffix trees and lots...

Field of application of clustering is spread across the all domain .. business intelligence, intuitive textual and multimedia search, document management ......
