# Filter for high-priority medicines

You can limit the results to combinations that include drugs from a custom group, such as high-priority medicines or other defined drug sets.

Define a Custom group first if you havent allready done so.

Then:

* Select **Filter** → **Drug** → **Custom drug groups**
* Choose the required Custom group

The Drug-Event Combinations table updates to display only combinations that include drugs from the selected custom group.

\
To modify an existing custom group or create a new one, see Create a Custom drug group.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://support.who-umc.org/vigilyze/quantitative-view/filter-for-high-priority-medicines.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
