        # @param [Fixnum] num
        #   Number of search results to return. * Valid values are integers between 1 and
        #   10, inclusive.
        # @param [String] or_terms
        #   Provides additional search terms to check for in a document, where each
        #   document in the search results must contain at least one of the additional
        #   search terms.
        # @param [String] q
        #   Query
        # @param [String] related_site
        #   Specifies that all search results should be pages that are related to the
        #   specified URL.
        # @param [String] rights
        #   Filters based on licensing. Supported values include: `cc_publicdomain`, `
        #   cc_attribute`, `cc_sharealike`, `cc_noncommercial`, `cc_nonderived` and
        #   combinations of these. See [typical combinations](https://wiki.creativecommons.
        #   org/wiki/CC_Search_integration).
        # @param [String] safe
        #   Search safety level. Acceptable values are: * `"active"`: Enables SafeSearch
        #   filtering. * `"off"`: Disables SafeSearch filtering. (default)
        # @param [String] search_type
        #   Specifies the search type: `image`. If unspecified, results are limited to
        #   webpages. Acceptable values are: * `"image"`: custom image search.
        # @param [String] site_search
        #   Specifies a given site which should always be included or excluded from
        #   results (see `siteSearchFilter` parameter, below).
        # @param [String] site_search_filter
        #   Controls whether to include or exclude results from the site named in the `
        #   siteSearch` parameter. Acceptable values are: * `"e"`: exclude * `"i"`:
        #   include
        # @param [String] sort
        #   The sort expression to apply to the results. The sort parameter specifies that
        #   the results be sorted according to the specified expression i.e. sort by date.
        #   [Example: sort=date](https://developers.google.com/custom-search/docs/
        #   structured_search#sort-by-attribute).
        # @param [Fixnum] start
        #   The index of the first result to return. The default number of results per
        #   page is 10, so `&start=11` would start at the top of the second page of
        #   results. **Note**: The JSON API will never return more than 100 results, even
        #   if more than 100 documents match the query, so setting the sum of `start + num`
        #   to a number greater than 100 will produce an error. Also note that the
        #   maximum value for `num` is 10.
        # @param [String] fields
        #   Selector specifying which fields to include in a partial response.
        # @param [String] quota_user
        #   Available to use for quota purposes for server-side applications. Can be any
        #   arbitrary string assigned to a user, but should not exceed 40 characters.
        # @param [Google::Apis::RequestOptions] options
        #   Request-specific options
        #
        # @yield [result, err] Result & error if block supplied
        # @yieldparam result [Google::Apis::CustomsearchV1::Search] parsed result object
        # @yieldparam err [StandardError] error object if request failed
        #
        # @return [Google::Apis::CustomsearchV1::Search]
        #
        # @raise [Google::Apis::ServerError] An error occurred on the server and the request can be retried
        # @raise [Google::Apis::ClientError] The request is invalid and should not be retried without modification
        # @raise [Google::Apis::AuthorizationError] Authorization is required
