# ListLogGroupsForQuery
<a name="API_ListLogGroupsForQuery"></a>

Returns a list of the log groups that were analyzed during a single CloudWatch Logs Insights query. This can be useful for queries that use log group name prefixes or the `filterIndex` command, because the log groups are dynamically selected in these cases.

For more information about field indexes, see [Create field indexes to improve query performance and reduce costs](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/CloudWatchLogs-Field-Indexing.html).
