        directly.

        Args:
            request (Union[google.cloud.recommendationengine_v1beta1.types.CollectUserEventRequest, dict]):
                The request object. Request message for CollectUserEvent
                method.
            parent (str):
                Required. The parent eventStore name, such as
                ``projects/1234/locations/global/catalogs/default_catalog/eventStores/default_event_store``.

                This corresponds to the ``parent`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            user_event (str):
                Required. URL encoded UserEvent
                proto.

                This corresponds to the ``user_event`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            uri (str):
                Optional. The url including cgi-
                arameters but excluding the hash
                fragment. The URL must be truncated to
                1.5K bytes to conservatively be under
                the 2K bytes. This is often more useful
                than the referer url, because many
                browsers only send the domain for 3rd
                party requests.

                This corresponds to the ``uri`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            ets (int):
                Optional. The event timestamp in
                milliseconds. This prevents browser
                caching of otherwise identical get
                requests. The name is abbreviated to
                reduce the payload bytes.

                This corresponds to the ``ets`` 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.api.httpbody_pb2.HttpBody:
                Message that represents an arbitrary HTTP body. It should only be used for
                   payload formats that can't be represented as JSON,
                   such as raw binary or an HTML page.

                   This message can be used both in streaming and
                   non-streaming API methods in the request as well as
                   the response.

                   It can be used as a top-level request field, which is
                   convenient if one wants to extract parameters from
                   either the URL or HTTP template into the request
                   fields and also want access to the raw HTTP body.

                   Example:

                      message GetResourceRequest {
                         // A unique request id. string request_id = 1;

                         // The raw HTTP body is bound to this field.
                         google.api.HttpBody http_body = 2;

                      }

                      service ResourceService {
                         rpc GetResource(GetResourceRequest)
                            returns (google.api.HttpBody);

                         rpc UpdateResource(google.api.HttpBody)
                            returns (google.protobuf.Empty);

                      }

                   Example with streaming methods:

                      service CaldavService {
                         rpc GetCalendar(stream google.api.HttpBody)
                            returns (stream google.api.HttpBody);

                         rpc UpdateCalendar(stream google.api.HttpBody)
                            returns (stream google.api.HttpBody);

                      }

                   Use of this type only changes how the request and
                   response bodies are handled, all other features will
                   continue to work unchanged.

                method.
            parent (str):
                Required. The parent eventStore resource name, such as
                ``projects/*/locations/*/catalogs/default_catalog/eventStores/default_event_store``.

                This corresponds to the ``parent`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            filter (str):
                Optional. Filtering expression to specify restrictions
                over returned events. This is a sequence of terms, where
                each term applies some kind of a restriction to the
                returned user events. Use this expression to restrict
                results to a specific time range, or filter events by
                eventType. eg: eventTime > "2012-04-23T18:25:43.511Z"
                eventsMissingCatalogItems
                eventTime<"2012-04-23T18:25:43.511Z" eventType=search

                We expect only 3 types of fields:

                ::

                   * eventTime: this can be specified a maximum of 2 times, once with a
                     less than operator and once with a greater than operator. The
                     eventTime restrict should result in one contiguous valid eventTime
                     range.

                   * eventType: only 1 eventType restriction can be specified.

                   * eventsMissingCatalogItems: specififying this will restrict results
                     to events for which catalog items were not found in the catalog. The
                     default behavior is to return only those events for which catalog
                     items were found.

                Some examples of valid filters expressions:

                -  Example 1: eventTime > "2012-04-23T18:25:43.511Z"
                   eventTime < "2012-04-23T18:30:43.511Z"

                   eventType = detail-page-view
                -  Example 3: eventsMissingCatalogItems eventType =
                   search eventTime < "2018-04-23T18:30:43.511Z"
                -  Example 4: eventTime > "2012-04-23T18:25:43.511Z"
                -  Example 5: eventType = search

                are:

                -  eventType - UserEvent.eventType field of type string.
                -  eventTime - in ISO 8601 "zulu" format.

                set to true, a sampling of events to be
                deleted will be returned.

            parent (str):
                Required.
                ``projects/1234/locations/global/catalogs/default_catalog/eventStores/default_event_store``

                This corresponds to the ``parent`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            request_id (str):
                Optional. Unique identifier provided by client, within
                the ancestor dataset scope. Ensures idempotency for
                expensive long running operations. Server-generated if
                unspecified. Up to 128 characters long. This is returned
                as google.longrunning.Operation.name in the response.
                Note that this field must not be set if the desired
                input config is catalog_inline_source.

                This corresponds to the ``request_id`` field
                on the ``request`` instance; if ``request`` is provided, this

                This corresponds to the ``input_config`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            errors_config (google.cloud.recommendationengine_v1beta1.types.ImportErrorsConfig):
                Optional. The desired location of
                errors incurred during the Import.

                This corresponds to the ``errors_config`` 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.api_core.operation.Operation:
                An object representing a long-running operation.
