Here are the advanced\nfeatures that are available:\n\n- [**Enterprise edition features**](#enterprise-features)\n\n- [**Advanced LLM features**](#advanced-llm-features)\n\n- [**Advanced website indexing**](#advanced-website-indexing)\n\nThe following table shows Vertex AI Search features and indicates the\nadvanced settings that are required for each feature:\n\n\n^\\*^ Core generative answer features include all answer generation\nfeatures except for advanced generative answer features, such as related\nquestions, query simplification, multi-step queries,\nmulti-turn queries, and multimodal answers that return images and charts.\n\n\n^†^Advanced generative answer features include all answer generation\nfeatures including related questions, query simplification, multi-step\nqueries, multi-turn queries, and multimodal answers that return images and\ncharts.\n\nEnterprise edition features\n---------------------------\n\nEnterprise edition features add functionality at the app level. Enterprise tier\nfeatures incur additional cost. For more information, see [Pricing](/generative-ai-app-builder/pricing).\nTurning on Enterprise edition features is required for the following features:\n\n- [Extractive answers](/generative-ai-app-builder/docs/snippets#extractive-answers).\n\n- [Extractive segments](/generative-ai-app-builder/docs/snippets#extractive-segments).\n\n- [Search tuning](/generative-ai-app-builder/docs/tune-search).\n\n- [Core generative answer features](/generative-ai-app-builder/docs/answer).\n\nIn addition, turning on Enterprise edition features is required for website\nsearch. That is, Enterprise edition features are required for any\nVertex AI Search app that uses [website data](/generative-ai-app-builder/docs/create-engine-es#website-data) (basic website search and\nadvanced website indexing). This\nsetting can't be turned off for apps that are attached to website data\nstores.\n\nIf you turn off Enterprise edition for an existing app, any features in your app\nthat require Enterprise edition will no longer work.\n\nTo change this setting for an existing app, see\n[Turn Enterprise edition on or off](/generative-ai-app-builder/docs/enterprise-edition).\n\nAdvanced LLM features\n---------------------\n\nAdvanced LLM features add generative AI functionality at the app level. Advanced\nLLM features incur additional cost. For more information, see\n[Pricing](/generative-ai-app-builder/pricing). Turning on advanced LLM features is required for the\nfollowing features:\n\n- [Search summarization](/generative-ai-app-builder/docs/get-search-summaries). For website search, this also\n requires [advanced website indexing](#advanced-website-indexing).\n\n- [Advanced generative answer features](/generative-ai-app-builder/docs/answer).\n For website search, this also requires\n [advanced website indexing](#advanced-website-indexing).\n\nIf you turn off advanced LLM features for an existing app, any functionality in\nyour app that requires advanced LLM features will no longer work.\n\nTo change this setting for an existing app, see\n[Turn advanced LLM features on or off](/generative-ai-app-builder/docs/advanced-llm).\n\nAdvanced website indexing\n-------------------------\n\nTurning on advanced website indexing generates an index for the websites that\nyou specify when you create your data store. This requires [domain\nverification](/generative-ai-app-builder/docs/domain-verification) and imposes a quota on the number of pages\nthat you can index. You can [upgrade this quota](/generative-ai-app-builder/quotas#request-a-quota-increase) if\nnecessary. Advanced website indexing incurs additional cost. For more\ninformation, see [Pricing](/generative-ai-app-builder/pricing) and\n[Quota for web page indexing](/generative-ai-app-builder/quotas#quota-for-webpage-indexing).\n\nAdvanced website indexing enables the features listed in the following table.\nThe table also indicates other advanced settings that are needed to enable a\nfeature.\n\nEnterprise edition features are required for any\nVertex AI Search app that uses [website data](/generative-ai-app-builder/docs/create-engine-es#website-data) for\nbasic website search or advanced website indexing.\n\nYou have the option to turn on advanced website indexing when\nyou create your data store and when you upgrade your data store.\nTo learn more about the upgrade process, see\n[Turn on advanced website indexing](/generative-ai-app-builder/docs/turn-on-advanced-indexing).\n\nYou cannot turn off advanced website indexing for an existing data store.\nInstead, you must create a new data store, and during the data store creation\nprocess, don't select the **Advanced website indexing** option."]]
