Scrapebox footprint for language?

I know that this footprint is to scrape edu url:
inurl:.edu

there are a footprint that scrape edu blog with specific language? german for example?

You need to take a better look on all the available footprints.

But more important, learn and try first all the search-operations at Google itself.
Then start using the Google Harvester.

To question: What you should do is, select "Google.DE" right under it. This will bring German site's.

You can also add stuff like:
intitle: typical German word

Be creative!
