How can I sort the results of a ZCatalog?

I try these:

return catalog({'meta_type': 'type1', 'multiplesvalues': 'value1'}, sort_on='multiplesvalues')

A requirement for this is that "multiplesvalues" is a "FieldIndex". Other types of indexes cannot be used for index based sorting.

... Module Products.ZCatalog.Catalog, line 577, in sortResults AttributeError: documentToKeyMap

Note that multiplesvalues is a keyword index and I need all objects that have value1 into multiplesvalues then sort by multiplesvalues

You cannot use index based sorting but must implement your own (external) sorting. -- Dieter
