# CloudWatch Logs Start Query

Schedules a query of a log group using CloudWatch Logs Insights. You specify the log group and time range to query and the query string to use.

For more information, see [CloudWatch Logs Insights Query Syntax](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/CWL_QuerySyntax.html).

Queries time out after 15 minutes of execution. If your queries are timing out, reduce the time range being searched or partition your query into a number of queries.
