I came up with a work-around using Python Methods.
The first part probably isn't necessary with 2.3.  It's only the dictionary 
that's important.

resa=self.catalog(title=query)
resb=self.catalog(summary=query)
resc=self.catalog(body=query)
res=resa[:len(resa)] + resb[:len(resb)] + resc[:len(resc)]

d = {}
for item in res:
         d.update( { item.data_record_id_ : item } )
return d.values()
