Thanks Angel for the detailed information. I have just upgraded from Search Services 2.0.0 and I am unable to search through custom metadata. Standard metadata search is working fine (cm:title, cm:description)


I noted that in my model i used a prefix that a shouldn't (dc) but i can't change it now that i have a couple of million documents.


Can you give me any hint?
