#list_cse_siterestricts(c2coff: nil, cr: nil, cx: nil, date_restrict: nil, enable_alternate_search_handler: nil, exact_terms: nil, exclude_terms: nil, file_type: nil, filter: nil, gl: nil, googlehost: nil, high_range: nil, hl: nil, hq: nil, img_color_type: nil, img_dominant_color: nil, img_size: nil, img_type: nil, link_site: nil, low_range: nil, lr: nil, num: nil, or_terms: nil, q: nil, related_site: nil, rights: nil, safe: nil, search_type: nil, site_search: nil, site_search_filter: nil, snippet_length: nil, sort: nil, start: nil, fields: nil, quota_user: nil, options: nil) {|result, err| ... } ⇒ Google::Apis::CustomsearchV1::Search

Returns metadata about the search performed, metadata about the engine used for the search, and the search results. Uses a small set of url patterns.

Parameters:

  • c2coff (String) (defaults to: nil) —

    Enables or disables Simplified and Traditional Chinese Search. The default value for this parameter is 0 (zero), meaning that the feature is enabled. Supported values are: * 1: Disabled * 0: Enabled (default)

  • cr (String) (defaults to: nil) —

    Restricts search results to documents originating in a particular country. You may use Boolean operators in the cr parameter's value. Google Search determines the country of a document by analyzing: * the top-level domain (TLD) of the document's URL * the geographic location of the Web server' s IP address See the Country Parameter Values page for a list of valid values for this parameter.

  • cx (String) (defaults to: nil) —

    The Programmable Search Engine ID to use for this request.

  • date_restrict (String) (defaults to: nil) —

    Restricts results to URLs based on date. Supported values include: * d[number] : requests results from the specified number of past days. * w[number]: requests results from the specified number of past weeks. * m[number]: requests results from the specified number of past months. * y[number]: requests results from the specified number of past years.

  • enable_alternate_search_handler (Boolean) (defaults to: nil) —

    Optional. Enables routing of Programmable Search Engine requests to an alternate search handler.

  • exact_terms (String) (defaults to: nil) —

    Identifies a phrase that all documents in the search results must contain.

  • exclude_terms (String) (defaults to: nil) —

    Identifies a word or phrase that should not appear in any documents in the search results.

  • file_type (String) (defaults to: nil) —

    Restricts results to files of a specified extension. A list of file types indexable by Google can be found in Search Console Help Center.

  • filter (String) (defaults to: nil) —

    Controls turning on or off the duplicate content filter. * See Automatic Filtering for more information about Google's search results filters. Note that host crowding filtering applies only to multi-site searches. * By default, Google applies filtering to all search results to improve the quality of those results. Acceptable values are: * 0: Turns off duplicate content filter. * 1: Turns on duplicate content filter.

  • gl (String) (defaults to: nil) —

    Geolocation of end user. * The gl parameter value is a two-letter country code. The gl parameter boosts search results whose country of origin matches the parameter value. See the Country Codes page for a list of valid values. * Specifying a gl parameter value should lead to more relevant results. This is particularly true for international customers and, even more specifically, for customers in English- speaking countries other than the United States.

  • googlehost (String) (defaults to: nil) —

    Deprecated. Use the gl parameter for a similar effect. The local Google domain (for example, google.com, google.de, or google.fr) to use to perform the search.

  • high_range (String) (defaults to: nil) —

    Specifies the ending value for a search range. * Use lowRange and highRange to append an inclusive search range of lowRange...highRange to the query.

  • hl (String) (defaults to: nil) —

    Sets the user interface language. * Explicitly setting this parameter improves the performance and the quality of your search results. * See the Interface Languages section of Internationalizing Queries and Results Presentation for more information, and Supported Interface Languages for a list of supported languages.

  • hq (String) (defaults to: nil) —

    Appends the specified query terms to the query, as if they were combined with a logical AND operator.

  • img_color_type (String) (defaults to: nil) —

    Returns black and white, grayscale, transparent, or color images. Acceptable values are: * "color" * "gray" * "mono": black and white * "trans": transparent background

  • img_dominant_color (String) (defaults to: nil) —

    Returns images of a specific dominant color. Acceptable values are: * "black"

    • "blue" * "brown" * "gray" * "green" * "orange" * "pink" * " purple" * "red" * "teal" * "white" * "yellow"

  • link_site (String) (defaults to: nil) —

    Specifies that all search results should contain a link to a particular URL.

  • low_range (String) (defaults to: nil) —

    Specifies the starting value for a search range. Use lowRange and highRange to append an inclusive search range of lowRange...highRange to the query.

  • lr (String) (defaults to: nil) —

    Restricts the search to documents written in a particular language (e.g., lr= lang_ja). Acceptable values are: * "lang_ar": Arabic * "lang_bg": Bulgarian * "lang_ca": Catalan * "lang_cs": Czech * "lang_da": Danish * "lang_de": German * "lang_el": Greek * "lang_en": English * "lang_es": Spanish * "lang_et": Estonian * "lang_fi": Finnish * "lang_fr": French * "lang_hr": Croatian * "lang_hu": Hungarian * "lang_id": Indonesian * " lang_is": Icelandic * "lang_it": Italian * "lang_iw": Hebrew * "lang_ja" : Japanese * "lang_ko": Korean * "lang_lt": Lithuanian * "lang_lv": Latvian * "lang_nl": Dutch * "lang_no": Norwegian * "lang_pl": Polish * "lang_pt": Portuguese * "lang_ro": Romanian * "lang_ru": Russian * " lang_sk": Slovak * "lang_sl": Slovenian * "lang_sr": Serbian * "lang_sv" : Swedish * "lang_tr": Turkish * "lang_zh-CN": Chinese (Simplified) * " lang_zh-TW": Chinese (Traditional)

  • num (Fixnum) (defaults to: nil) —

    Number of search results to return. * Valid values are integers between 1 and 10, inclusive.

  • or_terms (String) (defaults to: nil) —

    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.

    Query

  • related_site (String) (defaults to: nil) —

    Deprecated.

  • rights (String) (defaults to: nil) —

  • site_search_filter (String) (defaults to: nil) —

    Controls whether to include or exclude results from the site named in the siteSearch parameter. Acceptable values are: * "e": exclude * "i": include

  • snippet_length (Fixnum) (defaults to: nil) —

    Optional. Maximum length of snippet text, in characters, to be returned with results. Note: this feature is limited to specific engines. * Valid values are integers between 161 and 1000, inclusive.

  • sort (String) (defaults to: nil) —

    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.

  • start (Fixnum) (defaults to: nil) —

    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.

  • fields (String) (defaults to: nil) —

    Selector specifying which fields to include in a partial response.

  • quota_user (String) (defaults to: nil) —

    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.
