Search for resources in Knowledge Catalog

This document provides instructions on how to search for data assets in Knowledge Catalog.

Before you begin

Before you perform search, ensure that you are granted the required roles and have enabled the necessary API.

Required roles

To get the permissions that you need to search for entries and access search results in Knowledge Catalog, ask your administrator to grant you the following IAM roles:

For more information about granting roles, see Manage access to projects, folders, and organizations.

You might also be able to get the required permissions through custom roles or other predefined roles.

Asset-level permissions

Search results are scoped to your access level, independently of the selected project. To find an asset in Knowledge Catalog, you must have the appropriate read permissions for that resource in its underlying source system.

For example, finding a BigQuery table requires the roles/bigquery.metadataViewer role, while finding a Cloud SQL instance requires its equivalent Cloud SQL permissions. For more details, see Search scope.

Enable the API

Enable the Dataplex API.

Roles required to enable APIs

To enable APIs, you need the serviceusage.services.enable permission. If you created the project, then you likely already have this permission through the Owner role (roles/owner). Otherwise, you can get this permission through the Service Usage Admin role (roles/serviceusage.serviceUsageAdmin). Learn how to grant roles.

Enable the API

Search for resources

Console

To search for resources, follow these steps:

  1. In the Google Cloud console, go to the Knowledge Catalog Search page.

    Go to Search

  2. If you see the Try natural language search button prompt, click it. By default, natural language search is selected.

  3. In the Find resources across projects with natural language field, enter your query and then click Enter.

  4. To refine your search, click Filters.

    • Filters in multiple sections are evaluated with the AND logical operator.
    • Multiple filters within a single section are evaluated with the OR logical operator.

    The following filters are available:

    • Scope: search across the organization (default), the current project, or only for starred resources. For more information, see Search scope.
    • Systems: the Google Cloud service that the resource belongs to, such as BigQuery. The Knowledge Catalog system contains entry groups.
    • Projects: the projects to search in.
    • Type: the resource type, such as BigQuery connection, Cloud Storage bucket, or database. Depending on the resource type, you can also filter by subtype, such as the connection type or SQL dialect.
    • Select locations: the locations to search in.
    • Select datasets: the search results are limited to BigQuery resources that belong to the selected BigQuery datasets. In the Type to filter field, enter the name of the dataset.
    • Aspect types: the Knowledge Catalog aspect types that are associated with the resource that you're searching for. To filter by aspect values, click Filter on aspect type values, and then select the values.

  5. To view more information about the searched resource, click the resource name in the search results to open the entry details page.

Google Cloud CLI

To search for resources, use the gcloud dataplex entries search command:

gcloud dataplex entries search 'foo' \
  --project=PROJECT_ID \
  --semantic-search

Replace PROJECT_ID with the ID of the Google Cloud project.

REST

To search for resources, use the searchEntries method with the SemanticSearch parameter set to true.

POST https://dataplex.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION:searchEntries?query=foo&semanticSearch=true

Replace the following:

  • PROJECT_ID: the ID of your Google Cloud project
  • LOCATION: the region where the project exists (for example, us-central1)

View details of an asset returned by search

Console

Use Knowledge Catalog search to view the details of an asset.

  1. Search for an asset in Knowledge Catalog.

  2. In the search results, click the asset for which you want to view the details.

    The entry details page opens. The page includes the following sections:

    • Entry details: includes information such as the entry type, system, platform, fully qualified name, creation time, last modification time, description, and stewards.
    • Overview: an overview of the entry, if available.
    • Aspects: the required and optional aspects defined for the entry. For more information, see Categories of aspects.

gcloud

gcloud dataplex entries lookup command:

gcloud dataplex entries lookup ENTRY_ID \
  --entry-group=ENTRY_GROUP_ID \
  --location=LOCATION \
  --project=PROJECT_ID

Replace the following:

  • ENTRY_ID: the ID of the entry
  • ENTRY_GROUP_ID: the ID of the entry group
  • LOCATION: the region where the project exists
  • PROJECT_ID: the ID of the Google Cloud project

Limitations

Search has the following limitations:

  • Public resources are outside the scope of natural language search.
  • Aspects attached to entry links are outside the scope of natural language search.
