Hi Csaba, It’s difficult to give a general advice; XML documents are just too different. In principle, a few GB or even MB can be sufficient to create databases for very large collections (10 GB and more), but sometimes namespaces are a showstopper. See [1] for some statistics.
What’s the total size of your XML documents? Can you create the database if you enable the text and attribute index?
