From this page on the Java driver github docs (likely all of them), the parameters sent to the Google search are incorrect. The site is duplicated in the parameters
http://mongodb.github.io/mongo-java-driver/3.4/driver/tutorials/databases-collections/

In the search box, when I search for authentication, it does a Google search for
authentication site:mongodb.github.iomongodb.github.io/mongo-java-driver/3.4

The site field is not correct
