To: java-user@lucene.apache.org Date: Wednesday, July 22, 2009, 7:58 PM Hi, I'm relatively new to Lucene. I have the following case: I have indexed a bunch of documents. I then, query the index using IndexSearcher and retrieve the documents using Hits (I do know this is deprecated -- I'm using v 2.4.1). So, I do this for a set of queries and maintain which documents are returned to each one. In the end of it all, I have a list of documents maintained (more specifically, the hits.id(some_iterator_int) associated with the doc). Now, I wish to delete the documents which have not been returned for any query, from the index. How can I do this? My initial assumption was that I could retrieve all the doc ids from IndexReader and just traverse the list that I have maintained, if it is in the list, I don't delete it otherwise I do. Looking around didn't yield anything, and hence the mail. Any suggestions?
