# Define the data source

You can narrow the focus of a prompt by defining the data source, including the relevant collections. You can also filter the data to further refine the data source. Refining the scope of the data helps Ask AI retrieve more precise context and improves the relevance of responses, especially in large document sets.

To define sources in a conversation:

1. At the bottom of the Chat page, in the prompt box, select **Sources** ![](data:image/png;base64,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).
