# Query across all entities

***

Use the **Query Builder** to search hosts and processes across file, network, registry, and process events. You can also search Windows event logs and Linux system authentication logs.

For example, you can search for:

* All activity on a host.
* All activity initiated by a process on a host.

How to build a query

1. From Cortex AgentiX, select **Investigation & Response** → **Search** → **Query Builder**.
2. Select **ALL ACTIONS**.
3. Optional: Limit the scope to a specific acting process.

   Select **Add Process**. Then specify one or more attributes for the acting parent process.

   Use a pipe (`|`) to separate values. Use an asterisk (`*`) to match any characters.

   * **NAME**: Parent process name.
   * **PATH**: Parent process path.
   * **CMD**: Parent process command line, including arguments, up to 128 characters.
   * **MD5**: Parent process MD5 hash.
   * **SHA256**: Parent process SHA256 hash.
   * **USER NAME**: User who executed the process.
   * **SIGNATURE**: Parent process signing status.
   * **SIGNER**: Entity that signed the parent process certificate.
   * **PID**: Parent process ID.
   * **Run search on process, Causality and OS actors**: Applies the criteria to initiating processes. Clear this option to configure different attributes.
4. Optional: Limit the scope to an endpoint or its attributes.

   Select **Add Host**. Then specify one or more attributes:

   * **HOST**: **HOST NAME**, **HOST IP** address, **HOST OS**, **HOST ADDRESS**, or **INSTALLATION TYPE**.
   * **INSTALLATION TYPE**: Agent or data collector.
   * **PROCESS**: **NAME**, **PATH**, **CMD**, **MD5**, **SHA256**, **USER NAME**, **SIGNATURE**, or **PID**.

   Use a pipe (`|`) to separate values. Use an asterisk (`*`) to match any characters.
5. Specify the event time period.

   Select **Last 24H**, **Last 7D**, **Last 1M**, or **Custom**.
6. Choose when to run the query.

   Select the calendar icon to schedule it. Select **Run** to run it immediately. View results in the **Query Center**.

   You can leave the page while the query runs. You receive a notification when it completes. You can also **Cancel** the query or run a new query.
7. Review the query results.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-agentix/reference-and-developer-docs/cortex-agentix-xql/build-xql-queries/legacy-query-builder/query-across-all-entities.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
