Any number of records will still benefit from zebra indexing. You will get better ranking of results and more search capability, in addition to the performance. For maintenance ou need to schedule a cronjob to run and rebuild the index regularly (assuming new titles are being cataloged), but the space considerations are nominal. --joe On Thu, Jul 24, 2008 at 4:58 PM, Paul Yachnes <yach@cox.net> wrote:

How large a database (how many bibliographic records) do you need before you see any benefit in running Zebra?

What additional overhead/maintenance does running it require?
