# Query ## Overview The **Query** page can search and return metadata from either the Flat Model or the Graph Model of a commons. Using GraphQL, these searches can be tailored to filter and return fields of interest for the data sets being queried. These queries can be made immediately after data submission as this queries the model directly. ![BDC Query Page](/files/-M1RrMKmrZKdSkQwQ1w6) For more information about how to use the Query page, refer to the [Gen3 documentation](https://gen3.org/resources/user/query-data/). --- # Agent Instructions: 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: ``` GET https://bdcatalyst.gitbook.io/biodata-catalyst-documentation/written-documentation/explore-available-data/gen3-discovering-data/query.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
