This page shows how to preview search results for media apps using the Google Cloud console and how to get search results using the API.

To implement the search app, you can create a search widget to add to your web page or you can make API calls and integrate those calls into your webpage or application.

About search modes

There are several modes of search query for media apps:

Full queries: When end users intend for their whole search term or phrase to be searched for. For example, in a music streaming app, users type the whole title of the song and search for it in one go. This is a preferred way of searching when using an input interface that lets users search in one go, such as audio input or keyboard input.

In full queries, if the entry includes a spelling mistake, users expect that mistake to be corrected.

This is the same behavior as search for non-media (generic) apps. See Get search results for an app with structured or unstructured data.
Partial (or search-as-you-type) queries: When end users dynamically receive a new set of search results as they type each letter. For example, in a music streaming app, users start entering the name of the song they're searching for and with each letter they type, the search results dynamically update and narrow down.
Auto mode: Auto mode is a mix of full and partial modes. With auto mode, you let media search decide whether to return query results as partial or full.

To determine the end users' probable intent, media search analyzes and weights various signals, such as the number of letters entered, the speed of entry, and whether the entry is a recognized entity—for example, the name of an actor or movie.

Which mode to use

The default mode for media search queries is the auto mode. However, there are scenarios where you might choose to override the default mode and specify the full or partial query mode. Here are some use-case examples:

Scenario	Mode
You are very confident that your end users' queries are full queries. For example, you have a search box that includes an Enter function to mark the query complete and the user presses Enter.	Full queries
You are very confident that your end users' queries are intended as partial queries—that is, they are expecting the results list to update after each letter entered.	Partial queries
Neither of the above scenarios apply. Let media search decide whether to return query results as partial or full.	Auto

Get search results for a media app

You can preview search results from the Google Cloud console or get search results using the API. To get search results for a media app:

Console

To use the Google Cloud console to preview media search and to configure a widget:

In the Google Cloud console, go to the AI Applications page.

AI Applications
Click the name of the media search app.
Click Configurations.
Click the UI tab.
On the UI tab, set the General configurations and Data display options.
In the Preview pane, start typing a query.
To save the configurations and to make them available in the Integration tab, click Save and publish.

REST

Use the engines.servingConfigs.search method to get search results for a media app:

Find your app ID. If you already have your app ID, skip to the next step.
1. In the Google Cloud console, go to the AI Applications page.
  
  Go to Apps
2. On the Apps page, find the name of your app and get the app's ID from the ID column.
Run the following curl command to get search-as-you-type results.

All the fields except for contentSearchSpec can be used in conjunction with the searchAsYouTypeSpec field. For clarity, the optional fields have been omitted from the curl command. For the optional fields, see Get search results for an app with structured or unstructured data.
```
curl -X POST -H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "Content-Type: application/json" \
"https://discoveryengine.googleapis.com/v1/projects/PROJECT_ID/locations/global/collections/default_collection/engines/APP_ID/servingConfigs/default_search:search" \
-d '{
"query": "QUERY",
"searchAsYouTypeSpec": {"condition": "SPEC_CONDITION"}
}'
```
Replace the following:
- PROJECT_ID: the ID of your Google Cloud project.
- PROJECT_ID: the ID of your Google Cloud project.
- APP_ID: the ID of the Vertex AI Search app that you want to query.
- QUERY: the query text to search.
- SPEC_CONDITION: the search as you type spec can have one of the following values:
  - ENABLED: for partial queries
  - DISABLED: for full queries
  - AUTO: for partial or full as deemed appropriate. If you leave the SPEC_CONDITION field empty or don't specify it, the default search mode is AUTO.
Click for an example curl command.
```
curl -X POST -H "Authorization: Bearer $(gcloud auth print-access-token)"
-H "Content-Type: application/json"
"https://discoveryengine.googleapis.com/v1/projects/12345/locations/global/collections/default_collection/engines/my-app_4321/servingConfigs/default_search:search"
-d '{
     "query": "Mission Impossible",
     "searchAsYouTypeSpec": {"condition": "DISABLED"}
    }'
```
