            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, str]]): Strings which should be
                sent along with the request as metadata.

        Returns:
            google.cloud.aiplatform_v1.services.featurestore_service.pagers.SearchFeaturesPager:
                Response message for
