Link issues to a case
From the **Issues** page, select one or more issues that you want to link, right-click and select **Manage Issue → Link to case**. You can select one or more case to link the issues.
Unlink an issue from a case
From the **Issues** page, select the issue that you want to unlink, right-click and select **Manage Issue → Unlink from case**. You can select one or more cases to unlink the issue. You cannot bulk select issues to unlink.

## 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-xsiam/detect-investigate-and-respond-to-threats/investigation-and-response/investigate-issues/link-or-unlink-issues-from-a-case.md?ask=&goal=
```
`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.
