From the WPEngine Support Garage: Troubleshoot WordPress with the WP Engine Error Log
More specifically about LONG QUERY error:
Used to determine which queries of SELECT Statements could be optimized due to the character limit being over 1,024.
We have included it in the log to signify that the length of the query, which would be over 1,024 characters, is a Long Query and may be able to be optimized. We did not take any action on this query, it is just a notice to our customers. These only apply to Select statements, and not any other type of statements.
