Does anyone know how I can search a Z-Catalog for a using a time range. I tried to do the following but it doesn't seem to work: <dtml-in "catalog(bobobase_modification_time=_.ZopeTime( )-1, bobobase_modification_time_usage='range:max') I got this code snippet from the Advanced Z-Catalog Searching How To. Any suggestions would be greatly appreciated. email me at tom@bcswebservices.net
