# - Advanced uploading of files
#3. Click Assignment administration/Edit settings link.
#4. In the Crot block set up search parameters.
#5. Save settings and wait for the cron scheduler to process the assignments.
# IMPORTANT: setting cron on Moodle is covered in Moodle doc: https://docs.moodle.org/20/en/Cron
# If you are not sure how cron works on your server please ask your system administrator about it.
# Processing may consume a lot of time: it depends on the server power and external channel bandwidth.
# Global search consumes more time as it requires querying the search engine and downloading similar files from the Internet.
#6. Go to the assignment, click "View submitted assignments" link and you will see the maximum similarity score for submitted files.
#7. Open the link with similarity score and compare documents.
