## Description

In Cognigy.AI 2026.5.0, the Knowledge Search Node was removed. If you use this Node, it will still work, but you won’t be able to create new Knowledge Search Nodes. To ensure a seamless transition, we strongly recommend using the [Search Extract Output](https://docs.cognigy.com/ai/agents/develop/node-reference/other-nodes/search-extract-output) Node, as it offers the same functionality and additional features.

This Node searches and retrieves content from data that was previously uploaded to the Knowledge AI solution. Before using this Node, ensure that you have a `text-embedding-ada-002` LLM configured. Refer to the [list of supported providers](https://docs.cognigy.com/ai/agents/develop/gen-ai-and-llms/model-support-by-feature). To display the output of the Knowledge Search Node to the user, follow these steps:

1. In the Flow editor, add a Say Node below the Knowledge Search Node.
2. In the **Output Type** field, select **Text**.
3. In the **Text** field, click  and select the **KSearch:TopK Texts** Token.
4. Click **Save Node**.

## Parameters

### Knowledge Store
Select a store from the list to allow the Node to retrieve the data.
