hi Ian, Thanks for your reply. I am using the Lucene core 3.0 version. The index created will be accessed by the web application. The web application contains 4 nodes, clustered. What if all the nodes access the index. I think no any prob may raise. If i have a local index then what about it in the clustered environment? The NFS given is working good for saving the report, but only while i start the indexing the app freezes. it creates a lock file, i cant see whats happening inside as i cant see my console outputs too. And i have once more question. How do u update the index. As my scheduler keeps producing more reports to the file server, the index need to be updated then and there. how do i update the new report files to the index than doing again all the files. Or can i create a local index of the newly created reports and join this with the old index? any other professional solution?
