Update of /cvs-repository/Zope2/lib/python/SearchIndex
In directory serenade:/slab/home/chrism/sandboxes/CatalogBTreesIntegration/lib/python/SearchIndex

Modified Files:
      Tag: Catalog-BTrees-Integration
	UnIndex.py 
Log Message:
fixed apply_index to return an empty IISet instead of an empty OOSet when the index has no results to return... returning an OOSet was not working with weightedIntersection function in the catalog's _indexedResults method.
