What you do not want to happen is all the results to be grabbed and cached somehow. You only want to retrieve the actual documents being shown on that specific page. It looks like displaytag can support this, as long as you provide your own custom pruned document set. Personally, I use Tapestry :) Erik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Question How to Display the Contents for the Hits in Incremental order ? [ Each Time a re hit to the Mergerindex with Incremental X value ]. This would solve the problem of Out of Memory by prefetching all the hit in one strait go process. It is unwise, as you've seen, to prefetch the documents from Hits. Hits is designed for exactly what you're after. You can get the number of hits using hits.size(). My recommendation for paging through search results (and I'm using this extensively myself) in a web application is to simply display 25 results on one page - iterating *only* through those 25 desired. The link (or button) the user presses to go to the next or previous page passes the page number and query (search.jsp?query=some+querypage=2). Your server-side logic will search again, and start the hits iteration for 25 entries at 25 * the value of the page attribute. Lucene is plenty fast enough to allow this to work without much concern. Since your index is getting somewhat large, though, you probably do want to keep a persistent instance of IndexSearcher available on the server (perhaps in application scope). But a first pass implementation don't concern yourself with even that - just re-instantiate IndexSearcher for every search and see how fast things are. If its fast enough, leave well enough alone. Does this all make sense? Erik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
