Hi all, Thanks alot to Erik and others for your invaluable indications. I tried something simple today to calculate the similarity between two texts. I took the first text and indexed it and the second served as the query. The two texts are analysed by the same "Analyser". Then, at the end, I got the score of similarity between those two texts. Well, a question again, how does Lucene compute the score between a document and a query? I'll try Erik's recommendation later. Uddam
