Hi, this was clear actually. I was questionning the performance impact to call IndexReader.deleteDocument(int docNum) one million time. any information about that?
thanks, vincent Ian Lea <ian....@gmail.com> 14.09.2011 16:20 Please respond to java-user@lucene.apache.org To java-user@lucene.apache.org cc Subject Re: deleting with sorting and max document You don't do it with deleteDocuments() but with IndexReader.deleteDocument(int docNum), as I said. To spell it out a bit more: Execute a search to get a list of document ids, searching/sorting/whatever as you wish. Then loop through that list of document ids calling IndexReader.deleteDocument(int docNum) for each one. Hope that's clearer. -- Ian.
