properties are indexed in a catalog and the indexing works fine for most of them. One of the properties however is a multiple selction listbox, and this means that the property-type is a list. The ZCatalog doesn't seem to like this. It will not report any errors, but any searches in which the property is involved deliver a result set that is way too small. (I suspect that only those records are returned for which the multiple selection is empty.)

To index a list, use a Lines or Tokens property on your ZClass and a Keyword Index in the ZCatalog.

So basically using a multiple selection property in a ZClass makes that property unindexable? Wish i'd known that. The problem is my ZClass is alreday created and populated. Is there any chance of a solution other than deleting the property, adding it again as a lines or tokens type and reinserting all the values? eric
