+`is_tenant=true` parameter is optional, but specifying it provides storage with additional inforamtion about the usage patterns the collection is going to use.
+When specified, storage structure will be organized in a way to co-locate vectors of the same tenant together, which can significantly improve performance in some cases. 
+
+
 ## Limitations
 
 One downside to this approach is that global requests (without the `group_id` filter) will be slower since they will necessitate scanning all groups to identify the nearest neighbors.
