# Nodes

Contextual's Flow editor includes both Contextual-specific nodes as well as groups of nodes from the Node-RED community. In the Flow editor you will see nodes grouped into categories on the left-hand navigation. These can be easily searched.

Contextual-specific nodes worth noting include:

Object - These are custom nodes for interacting with Contextual's Object Types.

Request - These are nodes that leverage Contextual [Connections](/documentation-and-resources/components-and-data/connections.md) to connect with external APIs or messaging infrastructures like Kafka or Pulsar.

Event - Event nodes are for handling inbound and termination pages for event-based flows.

## 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://docs.contextual.io/documentation-and-resources/components-and-data/flows/nodes.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.
