authorDOCS users have access to a sample ClauseBank which contains publicly sourced provisions from the internet. To compare the text found in your contract with these provisions:
After running a review, click on the 
Icon next to any results in the review tab.
Click on the ClauseBank selector, and change it to "Sample Clauses". This should be "Mine + Team" by default.
You should now see sample clauses.
You can change the filters to find other types of clauses.
