That did make a difference, I now see the exact number of cluster i see from the workbench. I am of course interested in why the config changes did not have much effect. However, I am happy that by adding the threshold to my request URL produces the desired results
let me know if I can do any more tests and I will do so. Thanks much Ramdev On Mar 31, 2011, at 10:18 AM, Stanislaw Osinski wrote: I added the parameter as you suggested. (LingoClusteringAlgorithm.clusterMergingThreshold) into the searchComponent section that describes the Clustering module Changing the value of the parameter did not have any effect on my search results. However, when I used the Carrot2 workbench, I could see the effect of changing the value. (from 6 clusters it went down to 2 clusters) Interesting... Can you, for the sake of debugging, append &LingoClusteringAlgorithm.clusterMergingThreshold=0.0 to your request URL? S.
