This\nis because the global location provides better end-user response times and the\nfull feature set. See [Limitations for multi-regions](#limitations).\n\nMulti-regions\n-------------\n\nThe following table lists the multi-regions where\nAI Applications is available.\n\n| **Important:** All machine learning (ML) processes, such as training, prediction, and tuning a model, occur within the US when requests are made to regionally-available APIs in the US, or within the EU when requests are made to regionally-available APIs in Europe.\n\nSpecify a multi-region for your data store\n------------------------------------------\n\nTo confine your at-rest data to the US or EU multi-region, follow\nthese steps:\n\n1. If you create the data store through the Google Cloud console, then choose **us\n (multiple regions in the United States)** or **eu (multiple regions in the\n European Union)** when you pick your app location.\n\n For more information, see [Create a search\n app](/generative-ai-app-builder/docs/create-engine-es).\n2. For API calls, replace `discoveryengine` with `eu-discoveryengine` or\n `us-discoveryengine` and replace `global` with `eu` or `us`.\n\n For example, the path for the calls is: \n\n ```\n https://eu-discoveryengine.googleapis.com/v1/projects/PROJECT_ID/locations/eu/…\n ```\n\n or \n\n ```\n https://us-discoveryengine.googleapis.com/v1/projects/PROJECT_ID/locations/us/…\n ```\n\n instead of \n\n ```\n https://discoveryengine.googleapis.com/v1/projects/PROJECT_ID/locations/global/…\n ```\n3. Review the [limitations](#limitations) associated with using a specific\n multi-region.\n\nLimitations for multi-regions\n-----------------------------\n\nThe following features of AI Applications are supported globally but\nare not supported for the US and EU multi-regions or are supported in the\nmulti-regions in Preview:\n\n- **Autocomplete** : Although autocomplete is available in the US and EU\n multi-regions, the tail match suggestions and the advanced document data\n mode features cannot be used in multi-regions. For general information about\n autocomplete, see [Configure\n autocomplete](/generative-ai-app-builder/docs/configure-autocomplete).\n\n- **Basic website search:** For website data stores, you must use advanced website indexing.\n Basic website search is not available. For general information about\n Advanced website indexing, see [Advanced website\n indexing](/generative-ai-app-builder/docs/about-advanced-features#advanced-website-indexing).\n\n- **User events:** User events don't affect search results.\n\n- **Dynamic facets:** Even if a field is set to **Dynamic Facetable**,\n AI Applications does not use that field as a dynamic facet.\n\n- **Analytics:** Search analytics are available in Public preview in US and EU\n multi-regions. Viewing media recommendations analytics is global only. For\n general information about analytics, see [View\n analytics](/generative-ai-app-builder/docs/view-analytics).\n\n- **Media:** Media data stores are global only. You can't create media data\n stores for the US or EU multi-regions. For general information about media\n data stores, see [Create media apps and data\n stores](/generative-ai-app-builder/docs/create-app-media)\n and [About media documents and data\n stores](/generative-ai-app-builder/docs/media-documents).\n\nUsing multi-region APIs might not produce identical results to the global API."]]
