Your request rate is approaching the maximum that Google Scholar allows.
If you continue with the current query, your access may be blocked.

We recommend pausing until the 1-hour request rate has fallen below %u.

Do you want to execute the query anyway?

Google Scholar restricts the number of queries that any single user can perform during a given time period. This message indicates that you are getting close to the cut-off limit. Exceeding that limit may lead to a 24 hour lock-out, so the recommended approach is to pause a while before issuing the next query, to prevent this lock-out.

Click Yes to perform the query despite the potential block, or No to cancel the query.
