http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=11232 Bug ID: 11232 Summary: Retrieve facets from Zebra Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: new feature Priority: P5 - low Component: Architecture, internals, and plumbing Assignee: gmcharlt@gmail.com Reporter: dcook@prosentient.com.au QA Contact: testopia@bugs.koha-community.org At Kohacon, a few of us (Jared, Paul P, Tomas, myself, and possibly others) looked at using Zebra's native facetting. After a bit of trial and error, in the final 15 minutes of the hackfest, we were able to get it working using queries in YAZ(high fives all around), but I'm not sure if anyone has followed up on that work (as I've been on holiday). I don't see any existing bug reports for adding this functionality to Koha, but I think it would be preferable to how we build facets at the moment (hence this bug). This method should be: 1) faster (since it is pulling the facets from the search results using indexes rather than iterating through every record); 2) more comprehensive (it is based on the full result set and not just the first 50 or so results [depending on your sysprefs]); 3) able to build facets for control fields and the leader (since it pulls data using indexes, we should be able to easily build facets for publication year, record type, etc.). In terms of customizability (bug 10891), it might be more difficult to change on the fly. This is because we need to explicitly define each facet index in our configuration files for Zebra. I'll need to look over my notes and do a few more experiments, but I'm quite certain this is the case. While we could add a mechanism for allowing users to specify which facets to retrieve and display (probably a good idea), we couldn't do the same for the static XML config file. So we would need to either include all the indexes in the XML config file or mark it as a place for local changes. I'm not sure about the cost/benefit of telling Zebra that every index could be used as a facet. I don't imagine it would be too much of a cost though, since the list of facets would be fed to Zebra on start up and not runtime. -- As I said, I'm not sure if anyone is working on the native facetting at the moment. I would like to but I'll have to look at my workload and chat to my boss. I'll be happy to post my notes in a comment tomorrow on how to get it to work. The config is slightly different for DOM and GRS1 but it works well for both. -- You are receiving this mail because: You are watching all bug changes.
