 Advanced hunting is based on the [Kusto query language](https://docs.microsoft.com/azure/kusto/query/). You can use Kusto syntax and operators to construct queries that locate information in the [schema](advanced-hunting-schema-reference.md) specifically structured for advanced hunting. To understand these concepts better, run your first query.
