First, thanks for your reply. I was wondering about adding some extra clustering functionalities to Lucene. I wrote a clustering engine, based on hac/ahc and k-means algorithms based on Lucene search results. That work is based on a customized solution, and so I decided to write some general code . Right now I'm looking at this class com/mwroblewski/carrot/filter/ahcfilter/AHCFilter from carrot2 and found it to be very similar to my work;-) My aim is to provide some basic clustering functionalities to lucene search results. Carrot2 offers a lot of functionalities, like many inputs, I'm just trying to offer a simpler (much simpler!) clustering opportunity for lucene users. Hope I can get some good advices from you! ciao, Lorenzo
