 I've textindexng2 index which search in PrincipiaSearchSource + some 

 this error occours when I do this:

results = context.MyCatalog({'global_query': context.REQUEST['gquery']})
for result in results: <- here (line 8 above)

The catalog contains two types of objects: a container with metadata 
(derived from Folder) and a contained file (derived from File).

Other strange thing is that if I reindex some objects, the indexes 
content for that object change every time flipping from empty metadata 
and filled PrincipiaSearchSource to metadata filled and empty 

N.B. if I search with gquery='' I get all the cataloged object correctly.
