# Querying an inventory collection by using filters
<a name="inventory-query-filters"></a>

After you collect inventory data, you can use the filter capabilities in Amazon Systems Manager to query managed nodes that meet certain filter criteria. 

**To query nodes based on inventory filters**

1. Open the Amazon Systems Manager console at [https://console.amazonaws.cn/systems-manager/](https://console.amazonaws.cn/systems-manager/).

1. In the navigation pane, choose **Inventory**.

1. In the **Filter by resource groups, tags or inventory types** section, choose the filter box. A list of predefined filters is displayed.

1. Choose an attribute to filter on. For example, choose `AWS:Application`. If prompted, choose a secondary attribute to filter. For example, choose `AWS:Application.Name`. 

1. Choose a delimiter from the list. For example, choose **Begin with**. A text box is displayed in the filter.

1. Enter a value in the text box. For example, enter *Amazon* (SSM Agent is named *Amazon SSM Agent*). 

1. Press Enter. The system returns a list of managed nodes that include an application name that begins with the word *Amazon*.

**Note**  
You can combine multiple filters to refine your search.
