# Effects of deleting a field index policy
<a name="CloudWatchLogs-Field-Indexing-Deletion"></a>

If you delete a field index policy that has been in effect for a time, the following happens:
+ For up to 30 days after the policy is deleted, queries can still benefit from the indexed log events.
+ If you delete a log-group level index policy, and there is already an account-level policy in place that would apply to that log group, the account-level policy will eventually apply to that log group.
