You supply a query in the form of a text string or an image, and\nthe `default_config.search` method returns images for that query.\n| **Note:** Image search is not available using the Google Cloud console.\n\nBefore you begin\n----------------\n\nMake sure you satisfy the following prerequisites. Requirements vary depending\non whether you search using a text query or an image query.\n\n- If you search using a text query in your website search app, make sure the\n following is turned on: [Enterprise edition features](/generative-ai-app-builder/docs/about-advanced-features#enterprise-features)\n\n- If you search using an image query in your website search app, make sure the\n following are turned on:\n\n - [Enterprise edition features](/generative-ai-app-builder/docs/about-advanced-features#enterprise-features)\n\n - [Advanced website indexing](/generative-ai-app-builder/docs/about-advanced-features#advanced-website-indexing)\n\nPreview image search\n--------------------\n\nTo use the command line to preview image results for a website,\nuse the [`engines.servingConfigs.search`](/generative-ai-app-builder/docs/reference/rest/v1/projects.locations.collections.engines.servingConfigs/search) method:\n| **Note:** You can search over an app using the [`engines.servingConfigs.search`](/generative-ai-app-builder/docs/reference/rest/v1/projects.locations.collections.engines.servingConfigs/search) method and you can search over a data store using the [`dataStores.servingConfigs.search`](/generative-ai-app-builder/docs/reference/rest/v1/projects.locations.collections.dataStores.servingConfigs/search) method. For the following procedure, Google recommends searching using the `engines.servingConfigs.search` method.\n\n1. Find your app ID. If you already have your app ID, skip to the next step.\n\n 1. In the Google Cloud console, go to the **AI Applications** page.\n\n [Go to Apps](https://console.cloud.google.com/gen-app-builder/engines)\n 2. On the **Apps** page, find the name of your app and get the app's ID from\n the **ID** column.\n\n2. Call the\n [`engines.servingConfigs.search`](/generative-ai-app-builder/docs/reference/rest/v1/projects.locations.collections.engines.servingConfigs/search)\n method, specifying `1` for the `search_type`. Choose the method syntax\n depending on whether your query is\n text or image bytes.\n\n **Key Term:** In Vertex AI Search, the term *app* can be used interchangeably with the term *engine* in the context of APIs. \n\n ### Query is a text string\n\n curl -X POST \\\n -H \"Authorization: Bearer $(gcloud auth print-access-token)\" \\\n -H \"Content-Type: application/json\" \\\n -H \"X-Goog-User-Project: \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e\" \\\n \"https://discoveryengine.googleapis.com/v1/projects/\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e/locations/global/collections/default_collection/engines/\u003cvar translate=\"no\"\u003eAPP_ID\u003c/var\u003e/servingConfigs/default_config:search\" \\\n -d '{\n \"servingConfig\": \"projects/\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e/locations/global/collections/default_collection/engines/\u003cvar translate=\"no\"\u003eAPP_ID\u003c/var\u003e/servingConfigs/default_search\",\n \"query\": \"\u003cvar translate=\"no\"\u003eQUERY\u003c/var\u003e\",\n \"pageSize\": \"\u003cvar translate=\"no\"\u003ePAGE_SIZE\u003c/var\u003e\",\n \"offset\": \"\u003cvar translate=\"no\"\u003eOFFSET\u003c/var\u003e\",\n \"params\": {\"search_type\": 1}\n }'\n\n ### Query is an image\n\n curl -X POST \\\n -H \"Authorization: Bearer $(gcloud auth print-access-token)\" \\\n -H \"Content-Type: application/json\" \\\n -H \"X-Goog-User-Project: \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e\" \\\n \"https://discoveryengine.googleapis.com/v1beta/projects/\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e/locations/global/collections/default_collection/engines/\u003cvar translate=\"no\"\u003eAPP_ID\u003c/var\u003e/servingConfigs/default_search:search\" \\\n -d '{\n \"servingConfig\": \"projects/\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e/locations/global/collections/default_collection/engines/\u003cvar translate=\"no\"\u003eAPP_ID\u003c/var\u003e/servingConfigs/default_search\",\n \"imageQuery\": {\"imageBytes\":\"\u003cvar translate=\"no\"\u003eIMAGE_BYTES\u003c/var\u003e\"},\n \"pageSize\": \"\u003cvar translate=\"no\"\u003ePAGE_SIZE\u003c/var\u003e\",\n \"offset\": \"\u003cvar translate=\"no\"\u003eOFFSET\u003c/var\u003e\",\n \"params\": {\"search_type\": 1}\n }'\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e: the ID of your project.\n\n - \u003cvar translate=\"no\"\u003eAPP_ID\u003c/var\u003e: the ID of your app.\n\n - \u003cvar translate=\"no\"\u003eQUERY\u003c/var\u003e: the search query text.
