Hi All, I have a Lucene index built with Lucene 4.9 for 584 text documents, I need to extract a Document-term matrix, and Document Document similarity matrix in-order to use it to cluster the documents. My questions:1- How can I extract the matrix and compute the similarity between documents in Lucene.2- Is there any java based code that can cluster the documents from Lucene index. RegardsShaimaa
