Get started with media search

Get started with media search

You can quickly build a state-of-the-art media search app. Media search enables your audiences to discover content, with Google-quality results.

For general information about Vertex AI Search for media, see Introduction to media search and recommendations.

In this getting-started tutorial, you will use the Movielens dataset to demonstrate how to upload your media content catalog into Vertex AI Search. The Movielens dataset contains a catalog of movies (documents).

After uploading the movie data, you'll create a search app and test it through the preview page.

If you completed the Get started with media recommendations tutorial and you still have the data store (suggested name quickstart-media-data-store), then you can use that data store instead of creating another. In this case, you should begin the tutorial at Create an app for media search.

Estimated time to complete this tutorial: ~1 hour.

Objectives

• Learn how to import media documents to create a media data store.
• Create, configure and test a search app.

Before following this tutorial, make sure you have done the steps in Before you begin.

Prepare the dataset

Note: If you completed the Get started with media recommendations tutorial and you still have the data store (suggested name quickstart-media-data-store), skip to Create an app for media search.

You use the Cloud Shell to import the Movielens dataset and restructure the dataset for Vertex AI Search for media.

Open the Cloud Shell

1. Open Google Cloud console.
2. Select your Google Cloud project.
3. Take note of the project ID in the Project info card on the dashboard page. You will need the project ID for the following procedures.

4. Click the Activate Cloud Shell button at the top of the console. A Cloud Shell session opens inside a new frame at the bottom of the Google Cloud console and displays a command-line prompt.

   

Import the dataset

The Movielens dataset is available in a public Cloud Storage bucket to make it easier to import.

1. Run the following using your project ID to set the default project for the command-line.

   gcloud config set project PROJECT_ID
   

2. Create a BigQuery dataset:

   bq mk movielens
   

3. Load movies.csv into a new movies BigQuery table:

   bq load --skip_leading_rows=1 movielens.movies \
     gs://cloud-samples-data/gen-app-builder/media-recommendations/movies.csv \
     movieId:integer,title,genres
   

4. Load ratings.csv into a new ratings BigQuery table:

   bq load --skip_leading_rows=1 movielens.ratings \
     gs://cloud-samples-data/gen-app-builder/media-recommendations/ratings.csv \
     userId:integer,movieId:integer,rating:float,time:timestamp
   

Create BigQuery views

In this step, you will restructure the Movielens dataset so it follows the expected format for media data stores.

For this guide, you will create fake view-item user events during the past 90 days from positive ratings (< 4).

1. Create a view that converts the movies table into the Document schema:

   bq mk --project_id=PROJECT_ID \
    --use_legacy_sql=false \
    --view '
     WITH t AS (
       SELECT
         CAST(movieId AS string) AS id,
         SUBSTR(title, 0, 128) AS title,
         SPLIT(genres, "|") AS categories
         FROM `PROJECT_ID.movielens.movies`)
       SELECT
         id, "default_schema" as schemaId, null as parentDocumentId,
         TO_JSON_STRING(STRUCT(title as title, categories as categories,
         CONCAT("http://mytestdomain.movie/content/", id) as uri,
         "2023-01-01T00:00:00Z" as available_time,
         "2033-01-01T00:00:00Z" as expire_time,
         "movie" as media_type)) as jsonData
       FROM t;' \
   movielens.movies_view
   

   Now the new view has the schema that the Vertex AI Agent Builder API expects.

2. Go to the BigQuery page in Google Cloud console.

   Go to BigQuery

3. In the Explorer pane, expand your project name, expand the movielens dataset and click movies_view to open the query page for this view.

   

4. Go to the Table explorer tab.

5. In the Generated query pane, click the Copy to query button. The query editor opens.

6. Click Run to see movie data in the view that you created.

7. Create fictitious user events from movie ratings by running the following Cloud Shell command:

   bq mk --project_id=PROJECT_ID \
    --use_legacy_sql=false \
    --view '
    WITH t AS (
     SELECT
       MIN(UNIX_SECONDS(time)) AS old_start,
       MAX(UNIX_SECONDS(time)) AS old_end,
       UNIX_SECONDS(TIMESTAMP_SUB(
       CURRENT_TIMESTAMP(), INTERVAL 90 DAY)) AS new_start,
       UNIX_SECONDS(CURRENT_TIMESTAMP()) AS new_end
     FROM `PROJECT_ID.movielens.ratings`)
     SELECT
       CAST(userId AS STRING) AS userPseudoId,
       "view-item" AS eventType,
       FORMAT_TIMESTAMP("%Y-%m-%dT%X%Ez",
       TIMESTAMP_SECONDS(CAST(
         (t.new_start + (UNIX_SECONDS(time) - t.old_start) *
         (t.new_end - t.new_start) / (t.old_end - t.old_start))
       AS int64))) AS eventTime,
       [STRUCT(movieId AS id, null AS name)] AS documents,
     FROM `PROJECT_ID.movielens.ratings`, t
     WHERE rating >= 4;' \
     movielens.user_events
   

Activate Vertex AI Agent Builder

1. In the Google Cloud console, go to the Agent Builder page.

   Agent Builder

2. Read and agree to the Terms of Service, then click Continue and activate the API.

Create an app for media search

The procedures in this section guide you through creating and deploying a media search app.

1. In the Google Cloud console, go to the Agent Builder page.

   Agent Builder

2. Click Create app.

3. On the Create app page, select Search.

4. Under Content, click Media.

5. In the Your app name field, enter a name for your app such as quickstart-media-search. Your app ID appears under the engine name.

6. Click Continue.

7. If you completed the Get started with media recommendations tutorial and you still have the data store (suggested name quickstart-media-data-store), then select it, click Create, and skip to Preview search.

8. If you don't have a data store that contains the movielens dataset, create a new data store and select it:

   1. On the Data Stores page, click Create data store.

   2. Enter a display name for your data store, such as quickstart-media-data-store, and then click Create.

   3. Select the data store you just created, and then click Create to create your app. You will be redirected to the Select a data source page.

Import data

Next, import the movies and user events data that were formatted earlier.

Import documents

1. If you are not automatically redirected to the Select a data source page:

   • Open the Documents tab.
   • Click Import Data.

2. On the Select a data source page, select BigQuery.

3. Enter the name of the movies BigQuery view you created and click Import.

   PROJECT_ID.movielens.movies_view
   

4. Wait until all documents have been imported, which should take about 15 minutes. There should be 86537 documents when complete.

   You can check the Activity tab for the import operation status. When the import is complete, the import operation status changes to Completed.

Import user events

1. Open the Events tab.

2. Click Import Events.

3. Select BigQuery.

4. Enter the name of the user_events BigQuery view you created and click Import.
