        r"""Searches Data Catalog for multiple resources like entries and
        tags that match a query.

        This is a [Custom Method]
        (https://cloud.google.com/apis/design/custom_methods) that
        doesn't return all information on a resource, only its ID and
        high level fields. To get more information, you can subsequently
        call specific get methods.

        Note: Data Catalog search queries don't guarantee full recall.
        Results that match your query might not be returned, even in
        subsequent result pages. Additionally, returned (and not
        returned) results can vary if you repeat search queries.

        For more information, see [Data Catalog search syntax]
        (https://cloud.google.com/data-catalog/docs/how-to/search-reference).

        Args:
            request (Union[google.cloud.datacatalog_v1.types.SearchCatalogRequest, dict]):
                The request object. Request message for
                [SearchCatalog][google.cloud.datacatalog.v1.DataCatalog.SearchCatalog].
            scope (google.cloud.datacatalog_v1.types.SearchCatalogRequest.Scope):
                Required. The scope of this search request.

                The ``scope`` is invalid if ``include_org_ids``,
                ``include_project_ids`` are empty AND
                ``include_gcp_public_datasets`` is set to ``false``. In
                this case, the request returns an error.

                This corresponds to the ``scope`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            query (str):
                Optional. The query string with a minimum of 3
                characters and specific syntax. For more information,
                see `Data Catalog search
                syntax <https://cloud.google.com/data-catalog/docs/how-to/search-reference>`__.

                An empty query string returns all data assets (in the
                specified scope) that you have access to.

                A query string can be a simple ``xyz`` or qualified by
                predicates:

                -  ``name:x``
                -  ``column:y``
                -  ``description:z``

                This corresponds to the ``query`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            retry (google.api_core.retry.Retry): Designation of what errors, if any,
                should be retried.
            timeout (float): The timeout for this request.
            metadata (Sequence[Tuple[str, str]]): Strings which should be
                sent along with the request as metadata.

        Returns:
            google.cloud.datacatalog_v1.services.data_catalog.pagers.SearchCatalogPager:
                Response message for

        An entry group contains logically related entries together with
        `Cloud Identity and Access
        Management </data-catalog/docs/concepts/iam>`__ policies. These
        policies specify users who can create, edit, and view entries
        within entry groups.

        Data Catalog automatically creates entry groups with names that
        start with the ``@`` symbol for the following resources:

        -  BigQuery entries (``@bigquery``)
        -  Pub/Sub topics (``@pubsub``)
        -  Dataproc Metastore services
           (``@dataproc_metastore_{SERVICE_NAME_HASH}``)

        You can create your own entry groups for Cloud Storage fileset
        entries and custom entries together with the corresponding IAM
        policies. User-created entry groups can't contain the ``@``
        symbol, it is reserved for automatically created groups.

        Entry groups, like entries, can be searched.

        A maximum of 10,000 entry groups may be created per organization
        across all locations.

        You must enable the Data Catalog API in the project identified
        by the ``parent`` parameter. For more information, see `Data

                   role binding based on attributes about the request
