            transport (Optional[Union[str,FeaturestoreServiceTransport,Callable[..., FeaturestoreServiceTransport]]]):
                The transport to use, or a Callable that constructs and returns a new transport.
                If a Callable is given, it will be called with the same set of initialization

                Custom options for the client.

                1. The ``api_endpoint`` property can be used to override the
                default endpoint provided by the client when ``transport`` is
                not explicitly provided. Only if this property is not set and
                ``transport`` was not explicitly provided, the endpoint is
                determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment
                variable, which have one of the following values:
                "always" (always use the default mTLS endpoint), "never" (always
                use the default regular endpoint) and "auto" (auto-switch to the
                default mTLS endpoint if client certificate is present; this is
                the default value).

                2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable
                is "true", then the ``client_cert_source`` property can be used
                to provide a client certificate for mTLS transport. If
                not provided, the default SSL client certificate will be used if
                present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not
                set, no client certificate will be used.

                3. The ``universe_domain`` property can be used to override the
                default "googleapis.com" universe. Note that the ``api_endpoint``
                property still takes precedence; and ``universe_domain`` is

                your own client library.

        The progress of the import is tracked by the returned
        operation. The imported features are guaranteed to be
        visible to subsequent read operations after the
        operation is marked as successfully done.

        If an import operation fails, the Feature values
        returned from reads and exports may be inconsistent. If
        consistency is required, the caller must retry the same
        import request again and wait till the new operation
        returned is marked as successfully done.

        There are also scenarios where the caller can cause
        inconsistency.

         - Source data for import contains multiple distinct
          Feature values for    the same entity ID and
          timestamp.
         - Source is modified during an import. This includes
          adding, updating, or  removing source data and/or
          metadata. Examples of updating metadata  include but
          are not limited to changing storage location, storage
          class,  or retention policy.
         - Online serving cluster is under-provisioned.

        Args:
            request (Union[google.cloud.aiplatform_v1.types.SearchFeaturesRequest, dict]):
                The request object. Request message for
                [FeaturestoreService.SearchFeatures][google.cloud.aiplatform.v1.FeaturestoreService.SearchFeatures].
            location (str):
                Required. The resource name of the Location to search
                Features. Format:
                ``projects/{project}/locations/{location}``

                This corresponds to the ``location`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            query (str):
                Query string that is a conjunction of field-restricted
                queries and/or field-restricted filters.
                Field-restricted queries and filters can be combined
                using ``AND`` to form a conjunction.

                A field query is in the form FIELD:QUERY. This
                implicitly checks if QUERY exists as a substring within
                Feature's FIELD. The QUERY and the FIELD are converted
                to a sequence of words (i.e. tokens) for comparison.
                This is done by:

                - Removing leading/trailing whitespace and tokenizing
                  the search value. Characters that are not one of
                  alphanumeric ``[a-zA-Z0-9]``, underscore ``_``, or
                  asterisk ``*`` are treated as delimiters for tokens.
                  ``*`` is treated as a wildcard that matches characters
                  within a token.
                - Ignoring case.
                - Prepending an asterisk to the first and appending an
                  asterisk to the last token in QUERY.

                A QUERY must be either a singular token or a phrase. A
                phrase is one or multiple words enclosed in double
                quotation marks ("). With phrases, the order of the
                words is important. Words in the phrase must be matching
                in order and consecutively.

                Supported FIELDs for field-restricted queries:

                - ``feature_id``
                - ``description``
                - ``entity_type_id``

                Examples:

                - ``feature_id: foo`` --> Matches a Feature with ID
                  containing the substring ``foo`` (eg. ``foo``,
                  ``foofeature``, ``barfoo``).
                - ``feature_id: foo*feature`` --> Matches a Feature with
                  ID containing the substring ``foo*feature`` (eg.
                  ``foobarfeature``).
                - ``feature_id: foo AND description: bar`` --> Matches a
                  Feature with ID containing the substring ``foo`` and
                  description containing the substring ``bar``.

                Besides field queries, the following exact-match filters
                are supported. The exact-match filters do not support
                wildcards. Unlike field-restricted queries, exact-match
                filters are case-sensitive.

                - ``feature_id``: Supports = comparisons.
                - ``description``: Supports = comparisons. Multi-token
                  filters should be enclosed in quotes.
                - ``entity_type_id``: Supports = comparisons.
                - ``value_type``: Supports = and != comparisons.
                - ``labels``: Supports key-value equality as well as key
                  presence.
                - ``featurestore_id``: Supports = comparisons.

                Examples:

                - ``description = "foo bar"`` --> Any Feature with
                  description exactly equal to ``foo bar``
                - ``value_type = DOUBLE`` --> Features whose type is
                  DOUBLE.
                - ``labels.active = yes AND labels.env = prod`` -->
                  Features having both (active: yes) and (env: prod)
                  labels.
                - ``labels.env: *`` --> Any Feature which has a label
                  with ``env`` as the key.

                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, Union[str, bytes]]]): Key/value pairs which should be
                sent along with the request as metadata. Normally, each value must be of type `str`,
                but for metadata keys ending with the suffix `-bin`, the corresponding values must
