# AI features FAQ

There are many resources available to help you successfully work with Sitecore Content Hub including [best practices](https://doc.sitecore.com/ch/en/users/content-hub/general-best-practices.html "General best practices"), user documentation, cloud development documentation, and the [API/SDK documentation](https://doc.sitecore.com/ch/en/developers/cloud-dev/overview.html). You can also visit the Sitecore website for [additional resources](https://www.sitecore.com/resources/events-webinars?page=0).

> [!important]
> AI capabilities in Content Hub need to be enabled and, if necessary, configured by a *superuser* or a user with the necessary permissions granted to them through [user group policies](https://doc.sitecore.com/ch/en/users/content-hub/user-group-policies.html "User group policies"). Most AI capabilities require Sitecore Stream.

This topic provides answers to common questions about using the AI-assisted visual search feature of Content Hub.

## Why don't I have access to AI-assisted visual search?

AI features in Content Hub, including AI-assisted visual search, are Sitecore Stream capabilities.

## Why am I not getting the search results I expect?

This could be due to how you have worded your search query. The AI-assisted visual search brings up more accurate results when you provide a detailed description of what you are looking for. See [Best practices - Using visual search](https://doc.sitecore.com/ch/en/users/content-hub/using-visual-search.html "Using visual search").

## How is the relevance score used?

When an image is [uploaded for visual search](https://doc.sitecore.com/ch/en/users/content-hub/understanding-ai-services.html#UUID-16f3396c-af1f-3d9d-c5b4-faa93815e909_title-idm273482073039110), the AI service converts a representation of the image to a vector. This vector consists of a list of numbers that represent the visual characteristics of the image and is stored in ElasticSearch. This enables two types of searches:

- *Image-to-image search*, where a query image is converted in a vector and compared to vectors that are stored to find visually similar images.
- *Text-to-image search*, where a text query (such as sunset over mountains) is converted to a vector and used to find images that match the concept.

## How do I increase the number of search results returned?

Modify the visual search settings. See [Configure Sitecore AI for visual search](https://doc.sitecore.com/ch/en/users/content-hub/configure-sitecore-ai-for-visual-search.html "Configure Sitecore AI for visual search").

## How do I decrease the number of irrelevant results?

If you are seeing a lot of results that are not relevant to the search query, you can:

- Modify the visual search settings. See [Configure Sitecore AI for visual search](https://doc.sitecore.com/ch/en/users/content-hub/configure-sitecore-ai-for-visual-search.html "Configure Sitecore AI for visual search").
- [Upload more assets](https://doc.sitecore.com/ch/en/users/content-hub/upload-assets.html "Upload assets"). A larger number and a higher variety of assets will impact the relevancy of search results.

## Why are my brand kits not displaying in Content Hub?

Verify that they are published in Sitecore Stream and that you have configured brand kit integration.

## Why can't I access brand management?

You must be a superuser or be [assigned the necessary `ManageBrandKits` privilege](urn:resource:component:1694423).

## Why isn't the Enable feature available for the Brand Assistant?

Before you can enable the Brand Assistant, you must map the brand kits to the Content Hub entities.
