# Troubleshooting Query Timeouts

To troubleshoot timeout errors in Bulk API 2.0 query operations, apply additional filter criteria.

If you use a SOQL query with the `ORDER BY` clause, and you experience query time outs, then remove the `ORDER BY` clause before any subsequent troubleshooting. Use of `ORDER BY` in a Bulk 2.0 query disables PKChunking for the query. With PKChunking disabled, the query takes longer to execute, and potentially results in query timeouts.
