## Querying an index

* **Note**\
  You can use this code to filter document attributes. The topic [Filtering queries](https://github.com/kevinslin/aws-reference-notes/blob/main/services/amazon_kendra/filtering.md) contains examples that you can use to replace the following code.

## Query suggestions

* **Note**\
  The time for your updated settings to take effect depends on the updates you make and the number of search queries in your index.
* **Note**\
  Amazon Kendra learns new suggestions based on new queries added to the query log from the time you last cleared suggestions.

## Filtering on user context

* **Note**\
  User context filtering isn't an authentication or authorization control for your content. It doesn't do user authentication on the user and groups sent to the `Query` API. It is up to your application to ensure that the user and group information sent to `Query` API is authenticated and authorized.
