# Adding comments in queries

You can add comments in any section when building a query in Cortex Query Language (XQL).

* Comments are added on a single line using the following syntax.

  ```programlisting
   //<comments>
  ```

  For example,

  ```programlisting
  dataset = xdr_data
  | filter event_type=1
  //ENUM.process
  and event_sub_type = 1
  //ENUM.execution
  ```
* To write a comment that extends over multiple lines use the following syntax.

  ```programlisting
  /*multi-line <comments> */
  ```

  For example,

  ```programlisting
  dataset = xdr_data 
  | filter 
  /*multi-line Adding comments is a great thing.
  Here is an example */ 
  event_type=1
  ```

## 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/get-started-with-xql/xql-language-structure/adding-comments-in-queries.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.
