# Document cards

## **Important information cards**

When viewing a document, you could see up to four cards that display relevant information at a glance, saving you valuable research time.

![Information cards](/files/-McLj8lBLrBI2RA2gQDk)

**First card**

The type of information on this card will differ depending on the document type. However, it usually contains a variety of useful information about the document you are looking at, whether that is a list of parallel citations, information about the author, or the date of publication.

{% hint style="info" %}
Citations will always link to documents on vLex where possible.
{% endhint %}

### **Case law cards**

For case law, you will see three additional cards, outlined below:

#### **Key phrases**

This card summarises the top information that vLex can extract from the document. These are short sentences that will give you insight into what the document is about.

#### **Categories**

This card shows the areas of law relevant to a document. Select **Show all** to see all of the categories assigned to the case. Clicking any of the categories will open a new page listing all of the documents that have been tagged with that category.

#### Key paragraphs

This card highlights the sections of the case that have been most heavily relied upon by other cases. You can expand it by clicking **Show all**. As these sections of the judgment are most frequently cited in other cases, they are usually the most important.

When scrolling through a judgment, you will notice that any section that has been directly cited is highlighted in blue. The darker the shade of blue, the more frequently cited that section is. Click on any highlighted section to see where it has been cited. You can navigate to the most commonly cited passages of the judgment by using the scroll bar to the right of the document.

## 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://support.vlex.com/getting-started/documents/document-analysis.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.
