Sorry, not sure how I missed it then and now. It all works fine when you have `include_items: 1` in the conf file specified by preference OAI-PMH:ConfFile, but the item timestamps should be ignored when that's not the case. I'll post a patch. The thing with joins is that they are indeed quite terrible. If you only consider a range of one day, it all looks ok, but the way OAI-PMH harvesting usually works is that the initial harvest is done without date limits to get all the records, and then incremental harvesting is done with just a 'from' date (since the beginning of the previous harvesting). That means the date limits may include millions of records, and joins on such large sets are better avoided. I'll contact you off-bug for further discussion on the topic. You can check the history for these files to see how things have evolved in an attempt to improve functionality and performance. Also, I've just posted bug 27584 with a further refinement trying to address performance issues when there are millions of biblios. -- You are receiving this mail because: You are watching all bug changes.
